When destroying a connection, we need to check if we got to
full feature phase before freeing any io channels. This is because
the io channels are only allocated as part of a successful login.
The Calsoft iSCSI test suite has tests which will fail login.
Since the test system was just using a malloc backend with memcpy,
so even though a channel was NULL in some cases, it was never used
since the memcpy engine doesn't need it.
This prepares for some future patches which extend the use
of io channels in the bdev layer.

When performed limitation iSCSI tests, 128 target nodes with 1
connection for each target node, for IO bigger than 256KiB iSCSI
target will report run of out task pool issue sometimes. When
all the iSCSI parameters with default values, each connection
will consume maximum 189 tasks, we hardcoded the task pool with
16384, so 189 * 128 connection will exceed 16384. Increase the
default number from 16384 to 32768 will fix the issue.
With 1MiB block size and queue depth with 128 for each connection,
there will be 64 outstanding iSCSI commands in the iSCSI target,
for Writes, the maximum R2T number is 4, so the maximum tasks for
the 4 R2T is (1 + 16) * 4 = 68, 8KiB for the first burst task, 16
for the data segment. For Reads, the maximum 64 data in segment can
be used as 4 iSCSI Read commands. The rest 56 iSCSI commands will
cost 56 tasks, so the total number is 56 + 64 + 68 = 188, 1 additional
task for NOP task.

For large writes that require multiple SCSI tasks (one for immediate
data, then one or more for R2T-solicited data), we bump the refcount
for the task associated with the initial immediate data PDU, to
ensure it does not get freed until all of the child tasks are
completed. But in some cases this initial immediate data PDU could
complete after all of the R2T-soliciated data PDUs. The
completion code was not handling this case correctly which would
result in the iSCSI connection thinking it still had outstanding
SCSI tasks when the connection closed.

SPDK_NOTICELOG() can already do printf()-style formatting, so there is
no need to use snprintf() on a temporary buffer first.

There are some error paths that can get to spdk_iscsi_conn_stop_poller()
before the conn's session is set. So check whether the session is NULL
before trying to check its session type.

This ensures against races, when an existing session to a target node
stalls, causing the initiator to create a new session. These new
session's connection may get migrated to a different core than the
core of the stalled session.
In practice, this does not happen, but is a common occurrence when
debugging the iSCSI target using gdb.

This moves towards a single pair of functions where code can be placed
that must execute on the polling thread before the poller starts execution
and after the poller stops execution.

My previous pdu leak fixing patch breaks the
large logic for large read, and this patch
fixes this.

It is pdu memory leak issue. The reason is that
we did not correctly handle the read pdu task.

The lcore_id field in the get_iscsi_connections RPC was removed in
commit 5d8c94536a7d1d4c1f0ee3349188bf0e7e8c9e74; add a field to
spdk_iscsi_conn to track the lcore so this can be re-added.

This leaves more flexibility for future changes to the poller
representation without requiring API changes (after this one).
It also prevents the user from accidentally using poller fields in a
non-thread-safe way, since they can't be accessed directly anymore.
