[SCSI] lpfc 8.3.15: BSG, Discovery, and Misc fixes
- BSG interface related:
- Fix node reference count if node is active
- Warn if we're overwriting an active CT context
- Discovery related:
- Clear "Ignore Reg Login" flag when purging mailbox queue
- Pay attention to return code for fc_block_scsi_eh()
- Stall device loss code if we're almost done when it fires
(we're logged in, but PRLI is outstanding)
- Bugs
- Correct DIF code for endianness issues
- Correct where we had missed points to check txq on i/o
