During rmmod, all ndlp objects are cleaned up and marked with the NLP_DROPPED flag indicating that an ndlp object is currently being released. Thus, if an RSCN is received during driver unload, then walking the fc_nodes list to process the RSCN is unnecessary because the ndlp objects are very shortly going to be released. In the lpfc_rscn_recovery_check routine, early return if the driver is in the middle of unloading by checking for the FC_UNLOADING flag.
