NFSD: Optimize nfsd4_encode_fattr()

[ Upstream commit ab04de60ae1cc64ae16b77feae795311b97720c7 ]

write_bytes_to_xdr_buf() is a generic way to place a variable-length
data item in an already-reserved spot in the encoding buffer.

However, it is costly. In nfsd4_encode_fattr(), it is unnecessary
because the data item is fixed in size and the buffer destination
address is always word-aligned.
