[SCSI] qla2xxx: Update to dynamic logging.

This patch contains minor fixes to our new logging infrastructure:

- Remove extranous messages.
- Re-add 'nexus' and 'hdl' information.
- Adjusted the message ids to fill up the holes.
- Display FCP_CMND priority on update.
- Log only mail box error conditions.
- Do not print "Firmware ready **** FAILED ****" if cable is unplugged.
- Drop noisy 'fw_state...curr time...' message.
- Correct nexus display during abort.
- Add a special case error-logging set to '1'.
- Catagorize I/O exception display handling.
- Correct the bsg msg code printing.
- Dont use dynamic logging after host is removed.
