Subject: [PATCH] scsi: lpfc: Fix ndlp ref count for pt2pt mode issue RSCN
References: bsc#1076693
Git-commit: b7e50c536e8e4c6d4c74a1d54a0ce33edbf9dd0a
Patch-mainline: v4.16-rc1
pt2pt ndlp ref count prematurely goes to 0. There was reference removed
that should only be removed if connected to a switch, not if in
point-to-point mode.
Add a mode check before the reference remove.
