connection) to 127.0.0.1 (accept only connections from the local host).

Refactor the discover log page processing into a loop that calls a
function for each log page entry. This sets us up to add support for
multiple Get Log Page calls to handle larger discovery service lists.

This keeps the existing subsystem list (and therefore the discovery
service log page) in order when new subsystems are added dynamically.

For requests split in _nvme_ns_cmd_split_request() the payload offset is
set after children are created using recurrent call _nvme_ns_cmd_rw().
This makes impossible to reset SGL to proper offset in
incomming patches that split non-PRP complaint SGL requests.
To change this the payload offset is set after each request is allocated
in _nvme_ns_cmd_rw() not in _nvme_ns_cmd_split_request().

This bug was preventing multiple calls to spdk_nvme_probe() from
working, since the first call would return 0 from all of the DPDK driver
init callbacks and prevent other devices from ever being enumerated in
subsequent calls.

Simplify the arguments to nvme_transport_ctrlr_scan to take
a transport id that identifies the discovery service (or
NULL to scan PCIe).
Further, separate scan into two functions - scan and attach.
Scan is for scanning an entire bus, attach is for a specific
device.
