[SCSI] qla2xxx: Group CS_RESET return status with other link level event statuses.

Currently when we receive a CS_RESET as a response for a SCSI command the
driver will return DID_TRANSPORT_DISRUPTED back to the SCSI mid-layer.  There
are certain circumstances where this could cause the mid-layer to exhaust all of
its retries if the FC port goes away for a short time.  This will result in
commands being prematurly failed.  Moving the CS_RESET return code to be
grouped with other link level events will cause the FC transport layer to block
that target's queue thus preventing the premature exhaustion of retries.
