scsi: fnic: changing queue command to return result DID_IMM_RETRY when rport is init
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. Signed-off-by: Sesidhar Baddela <sebaddel@cisco.com> Signed-off-by: Satish Kharat <satishkh@cisco.com> Signed-off-by: Martin K.
