[SCSI] lpfc 8.2.4 : Miscellaneous Fixes 

Miscellaneous Fixes:
- Fix a couple of sparse complaints
- Reset the FCP recovery flag when the node is not a FCP2 device.
- Speed up offline prep delays
- Fixed a memory leak in lpfc_mem_alloc failure path
- Fixed external loopback test.
- Fixed error code returned from the driver when HBA is over heated.
- Correct Max NPIV vport to limits read from adapter
- Add missing locks around fc_flag and FC_NEEDS_REG_VPI
- Add missing hba ids for device identification
- Added support for SET_VARIABLE and MBX_WRITE_WWN mailbox commands
- Changed all temperature event messages from warning to error
- Fix reporting of link speed when link is down
- Added support for MBX_WRITE_WWN mailbox command
- Change del_timer_sync() in ISR to del_timer() in interrupt handler
- Correct instances of beXX_to_cpu() that should be cpu_to_beXX()
- Perform target flush before releasing node references on module unload
- Avoid bogus devloss_tmo messages when driver unloads
- Fix panic when HBA generates ERATT interupt
- Fix mbox race condition and a workaround on back-to-back mailbox commands
- Force NPIV off for pt2pt mode between 2 NPorts
- Stop worker thread before removing fc_host.
- Fix up discovery timeout error case due to missing clear_la
- Tighten mailbox polling code to speed up detection of fast completions
- Only allow DUMP_MEMORY if adapter offline due to overtemp errors
- Added extended error information to the log messages in chip init.
