Subject: scsi: fnic: changing queue command to return result DID_IMM_RETRY when rport is init
References: bsc#1035920
Git-commit: 4a1108d6caf7cd0f15d439bee6163ba00c7c1b33
Patch-Mainline: v4.13-rc1

Currently the queue command returns DID_NO_CONNECT anytime the rport is
not in RPORT_ST_READY state. Changing it to return DID_NO_CONNECT only
when the rport is in RPORT_ST_DELETE state. When the rport is in one of
the init states retruning DID_IMM_RETRY.
