In NPIV environment, a NPIV host may use a queue pair created
by base host or other NPIVs, so the check for a queue pair
created by this NPIV is not correct, and can cause an abort
to fail, which in turn means the NVME command not returned.
This leads to hang in nvme_fc layer in nvme_fc_delete_association()
which waits for all I/Os to be returned, which is seen as hang
in the application.
