[SCSI] qla2xxx: Return DID_NO_CONNECT when FC device is lost.
If the target device gets lost, this fix is needed, as it causes negative unintended responses on basic I/O tests. If the target device gets lost, the upstream qla2xxx driver returns SCSI_MLQUEUE_TARGET_BUSY which causes an immediate retry without drop in the number of allowed retries. This semantic change, as a result of removing FC_DEVICE_LOST check is reasonable, as it only extends a short transitional period, until the transport is called to notify that the rport as lost (fc_remote_port_delete()). Once transport notification is done, fc_remote_port_chkready() check will take over.
