Miscellaneous fixes:
- Fix ERRATT flag which was overlapping
- Allow RESTART mbx commands through when stopped.
- Accept incoming PLOGI when connected to an N_Port.
- Fix NPort to NPort pt2pt problems: ADISC and reg_vpi issues
- Fix vport unloading error that erroneously cleaned up RSCN buffers
- Fix memory leak during repeated unloads - in mbox handling
- Fix link bounce vs FLOGI race conditions
