NFSD: Use a bitmask loop to encode FATTR4 results
The fattr4 encoder is now structured like the COMPOUND op encoder: one function for each individual attribute, called by bit number. Benefits include: - The individual attributes are now guaranteed to be encoded in bitmask order into the send buffer - There can be no unwanted side effects between attribute encoders - The code now clearly documents which attributes are /not/ implemented on this server Reviewed-by: Jeff Layton <jlayton@kernel.org> Signed-off-by: Chuck Lever <chuck.lever@oracle.com>
