[SCSI] lpfc 8.2.6 : Miscellaneous Fixes 

Miscellaneous Fixes
- Allow WRITE_VPARAM command when the virtual port is in a stopped state
- Fixed handling of our queue depth max that was unconditionally raising
  the depth on all vports, rather than just the vport affected.
- Fix race in interrupt handler for mailbox processing that did not take
  out the host lock.
- Removed unused functions: find_node, findnode_rpi, and fabric_abort_flogi
- Correct misspelled word unsolicited in message 0146
- Correct HW-error 5 handling - it should not reset the adapter
- Correct handling of IOCBs, which did not null out our pCmd field before
  invoking the midlayer io done function.
- Changed our maximum supported target id to 4096
