[SCSI] lpfc 8.2.8 : Miscellaneous Bug Fixes

Miscellaneous Fixes:
- Fix the wrong variable name used for checking node active usage status
- Fix numerous duplicate log message numbers
- Fix change KERN_WARNING messages to KERN_INFO.
- Stop sending erroneous LOGO to fabric after vport is already terminated
- Fix HBQ allocates that were kalloc'ing w/ GFP_KERNEL while holding a lock.
- Fix gcc 4.3.2 compiler warnings and a sparse warning
- Fix bugs in handling unsolicited ct event queue
- Reorder some of the initial link up checks, to remove odd VPI states.
- Correct poor VPI handling
- Add debug messages
- Expand Update_CFG mailbox definition
- Fix handling of VPD data offsets
- Reorder loopback flags
- convert to use offsetof()
