scsi: lpfc: Fix lack of device removal on port swaps with PRLIs
During target port-swap testing with link flips, the initiator could
encounter PRLI errors. If the target node disappears permanently, the ndlp
is found stuck in UNUSED state with ref count of 1. The rmmod of the driver
will hang waiting for this node to be freed.
While handling a link error in PRLI completion path, the code intends to
skip triggering the discovery state machine. However this is causing the
final reference release path to be skipped. This causes the node to be
stuck with ref count of 1
Fix by ensuring the code path triggers the device removal event on the node
state machine.
