[SCSI] qla2xxx: Rework firmware-trace facilities.
- Defer firmware dump-data raw-to-textual conversion to
user-space.
- Add module parameter (ql2xallocfwdump) to allow for per-HBA
allocations of firmware dump memory.
- Dump request and response queue data as per firmware group
request.
- Add extended firmware trace support for ISP24XX/ISP54XX chips.
