3.18-stable review patch. If anyone has any objections, please let me know.
------------------
From: Benjamin Coddington <bcodd...@redhat.com>
commit bf7491f1be5e125eece2ec67e0f79d513caa6c7e upstream.
Fix a bug where nfsd4_encode_components_esc() incorrectly calculates the
length of server array in fs_location4--note that it is a count of the
number of array elements, not a length in bytes.

Fixes: 082d4bd72a45 (nfsd4: "backfill" using write_bytes_to_xdr_buf)
