Subject: [ 051/167] nfsd: fix endianness breakage in TEST_STATEID handling

3.2-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Al Viro <viro@...iv.linux.org.uk>

commit 02f5fde5df0ea930e70f93763dd48beff182b208 upstream.

->ts_id_status gets nfs errno, i.e. it's already big-endian; no need
to apply htonl() to it.  Broken by commit 174568 (NFSD: Added TEST_STATEID
operation) last year...
