nvme-fc: on lldd/transport io error, terminate association

Browse source

Per FC-NVME, when lldd or transport detects an i/o error, the
connection must be terminated, which in turn requires the association
to be termianted.  Currently the transport simply creates a nvme
completion status of transport error and returns the io. The FC-NVME
spec makes the mandate as initiator and host, depending on the error,
can get out of sync on outstanding io counts (sqhd/sqtail).

Implement the association teardown on lldd or transport detected
errors.
