[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.
