Subject: [PATCH] scsi: lpfc: correct port registrations with nvme_fc
References: bsc#1076693
Git-commit: 3b5bde69bcf91d75e75d6b0ca9ab6346d0744137
Patch-mainline: v4.16-rc1

The driver currently registers any remote port that has NVME support.
It should only be registering target ports.

Register only target ports.
