[SCSI] lpfc driver 8.0.30 : fix lip/cablepull panic
Fix panic on lip and cable pull Symptoms: Panic on lip or cable pull Cause: Use after free of nlp in lpfc_nlp_remove() Fix: Do not make FC transport calls after a node is removed. Transport calls are disabled by ignoring the initial delete transition. Signed-off-by: James Smart <James.Smart@emulex.com> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
