With faulty cables in PT2PT topology, an unintentional ndlp double kref
decrement can occur.
If a FLOGI request is outstanding before the link goes down, the missing
FLOGI_ACC causes an F_Port ndlp to remain in the UNUSED state. During link
down, lpfc_cleanup_rpis is called and decrements an ndlp kref.
Additionally, when the driver later decides to abort the FLOGI, the FLOGI
completion handler decrements the ndlp kref a second time.
Remove duplicate clean up logic in lpfc_cleanup_rpis because the updated
FLOGI completion handler already handles the ndlp kref decrement.
