NFS: Import NFS3ERR definitions
enum nfs_stat in uapi/linux/nfs.h collects the on-the-wire status
codes for every NFS version under version-agnostic NFSERR_* names.
The in-kernel NFS client and server reference these names
internally, which drags uapi/linux/nfs.h into many translation
units that need nothing else from that header.
xdrgen conversion will provide spec-based definitions of the NFS
status enum constants. Replacing the existing internal references
with version-specific names requires a version-specific spelling
for each code that NFSD uses.
linux/nfs4.h already supplies the NFSv4 codes, but NFSv3 has no
counterpart header, and not every NFSv3 code has an NFS4ERR_*
spelling: NFSERR_NOT_SYNC (10002) and NFSERR_REMOTE (71) have no
NFSv4 equivalent at all, and NFSERR_JUKEBOX (10008) appears in
NFSv4 as NFS4ERR_DELAY.
Introduce the NFSv3 status codes as NFS3ERR_* in linux/nfs3.h so a
subsequent patch can respell NFSD's status definitions without
relying on uapi/linux/nfs.h.
