[PATCH] lpfc 8.1.3: Protect NPL lists with host lock
Protect NPL lists with host lock
Symptoms: lpfc_findnode_rpi and lpfc_findnode_did can be called
outside of the discovery thread context. We have to iterate
through the NPL lists under the host lock and all add/del
operations on those lists have to be done under host lock.
