This patch is close to the end of the effort to unify buffer allocation
among NVMe-oF transports.
Merge each transport's fill_buffers() into common
spdk_nvmf_request_get_buffers() of the generic NVMe-oF transport.
One noticeable change is to set req->data_from_pool to true not in
each specific transport but in the generic transport.
The next patch will add spdk_nvmf_request_get_multi_buffers() for
multi SGL case of RDMA transport.
This relatively long patch series is a preparation to support
zcopy APIs in NVMe-oF target.

nvmf_rdma_fill_wr_sgl_with_md_interleave().
In nvmf_rdma_fill_wr_sgl(), pass DIF context, remaining data block
size, and offset to nvmf_rdma_fill_wr_sge() in the while loop.
For non DIF case, initialize all of them by zero.
In nvmf_rdma_fill_wr_sge(), classify non-DIF case and DIF case
by checking if DIF context is NULL.
As a minor change of wording, remaining is sufficiently descriptive
and simpler than remaining_io_buffer_length and so use remaining.

This is a preparation to support per portal group CHAP authentication
for discovery session.
Previously require_chap, disable_chap, and mutual_chap had been set
and used in iscsi_negotiate_param(), and chap_group had been set
and used in iscsi_get_authinfo().
If a connection is in a discovery session, the connection can get
all CHAP params at its creation, spdk_iscsi_conn_construct().
If a connection is in a normal session, the connection can get all
CHAP params in iscsi_op_login_negotiate_chap_param().
Each connection is in either discovery session or normal session.
So the following change is possible and is done in this patch.
spdk_iscsi_conn_construct() sets all CHAP params of the connection
by global parameters. Then iscsi_op_login_negotiate_chap_param()
overwrites them by the corresponding target's parameters.
iscsi_negotiate_chap_param() and iscsi_get_authinfo() just refer
the CHAP params.
Besides, iscsi_get_authinfo() changed to call just
spdk_iscsi_chap_get_authinfo() inside, and so inline
spdk_iscsi_chap_get_authinfo() into iscsi_auth_params() and then
remove iscsi_get_authinfo().

The previous version of this function precluded one target name from
being a leading substring of another. i.e. if "nvmf_tgt_1" was already
used as a name "nvmf_tgt_11" could not be used subsequently.
Just an odd quirk that shouldn't be the case.

The current connection scheduling mechanism (RoundRobin) doesn't take into account the qpair type and assigns each new qpair to the next poll group. As a side effect there might occur a disbalance when some poll group handles more IO qpairs than others. In RDMA transport it is possible to get the qpair type before the controller creation using a private data from the rdma_cm event, this allows to schedule admin and IO qpairs in the balanced way.

Operations with poll groups list must be protected by rtransport->lock.
Make rtranposrt->lock recursive to avoid unnecessary mutex operations when
the poll group is being destroyed within spdk_nvmf_rdma_poll_group_create

On a DIF verification error, fail the read command with a status code
of APPLICATION_TAG_CHECK_ERROR, GUARD_CHECK_ERROR, or
REFERENCE_TAG_CHECK_ERROR and a status code type of SCT_MEDIA_ERROR.
The state of the request is TCP_REQUEST_STATE_TRANSFERRING_CONTROLLER_TO_HOST
when a DIF verification error is detected. So dequeue the request
from C2H data queue, return the response PDU, and then send the command
response.
This was an item on the TODO list. RDMA transport do this right
behavior from the start and so TCP transport follows it by this patch.

tcp_req->orig_length had been set just before I/O submission but
the value is already fixed in spdk_nvmf_tcp_req_parse_sgl().
Hence move setting tcp_req->orig_length accordingly.
This follows the good practice of RDMA transport.
