NFSD: Move pre-xdr'ed status codes out of nfsd.h

nfsd.h is included by nearly every NFSD translation unit, so its
include of <linux/nfs4.h> reaches all of them, whether or not they
touch NFSv4. That include existed solely for the block of pre-xdr'ed
nfserr_* values at the end of the file: several of those values,
such as nfserr_delay and nfserr_admin_revoked, are built from
NFS4ERR_* constants defined in nfs4.h. The NFSD-internal error enum
that follows the block (NFSERR_EOF and friends) is anchored at an
impossible nfsstat4 value, thus it also needs nothing from nfs4.h.
But these codes are used by all NFS versions, so their new home must
be version-neutral.

Move the pre-xdr'ed value block and the internal error enum into a
new fs/nfsd/nfserr.h, which includes nfs4.h itself, and drop the
nfs4.h include from nfsd.h. Include nfserr.h directly from each
translation unit that references the pre-xdr'ed values or the
internal error codes, rather than carrying it in a widely-included
header.

A translation unit that includes nfsd.h without using the error
block no longer pulls in nfs4.h. The ones that reference the block
can still reach it through nfserr.h.
