The following 3 patches start the sync up with FC-NVME-2 rev 1.06.
The first patch updates the nvme-fc.h header to match the spec
The second patch updates the existing transport to match the
header - where field names may have changed.
The last patch updates the CMD IU for a new "category" field that
identifies the command set type for the io - needed by analyzer
guys to decode the sqe.
Subsequent patches will be coming to add new behavioral changes.
Older implementations should continue to work fine, with new
behaviors enabling new features.

Sync the header to FC-NVME-2 r1.06 (T11-2019-00210-v001).
Includes some minor mods where pre-release field names changed
by the time the spec was released.
