[SCSI] lpfc 8.2.2 : Error messages and debugfs updates

Error messages and debugfs updates:
 - Fix up GID_FT error messages
 - Enhance debugfs with slow_ring_trace, dumpslim and nodelist information
 - Add log type (and messages) for vport state changes
 - Enhance log messages when retries ELS fail
