bouyer fc92601259 Fixes related to QUEUE FULL status:
- move status handling in siop_scsicmd_end(), it's better than in siop_intr()
- define 2 internal SIOP status, for "no status reported by device" and
  reset condition
- add a list of "urgent" command, to be executed before the list of command
  queued the normal way; this is used for command which got aborted
  by a QUEUE FULL and have to be requeued in order.
- Don't accept to send a Q_TAG message not immediatly folowing a IDENTIFY
