[PATCH] nvme-fabrics: patch target code in prep for FC transport support

[James Smart]

Patch nvme-fabrics target code in prep for FC transport support:
- Add FC transport type decoding
- Add FC address family decoding

Patch is cut against the linux-nvme for-4.8/drivers branch

Note: this patch had been posted to the prior nvme fabrics repository but
not merged before being brought over to linux-nvme.
