scsi: lpfc: Fix NPIV Fabric Node reference counting
While testing initiator-side cable swaps with NPIV, oops occur. The
reference counts for the Fabric nodes on the NPIV vports isn't balanced,
resulting in premature node removal.
The following fixes were made:
- Removed the FC_LBIT check in lpfc_linkup_port. This removed the special
case for vports that didn't have them clean up just like the physical
port.
- Removed the unreg_rpi call in lpfc_cleanup_node. In this section, the
node is being removed in the context of a reference count release and a
mailbox command can't be issued at this point.
- Remove special case handling in the default mailbox completion handler
that allowed the skipping of a node reference. Now, reference counting
always requires the removal of the reference.
- Move the location of the DEVICE_RM event is done during LOGO handling as
the driver has additional work to do on the ndlp before puts/releases
can be performed.
