Subject: nvme-fc: move remote port get/put/free location
Patch-mainline: v4.15-rc1
Git-commit: 469d0ef06debe29ec60350b9976a520c4ad5a1e8
References: FATE#323952, FATE#322506

move nvme_fc_rport_get/put and rport free to higher in the file to
avoid adding prototypes to resolve references in upcoming code additions
