[PATCH 3.12 059/182] nfsd4: fix test_stateid error reply encoding

[Jiri Slaby]

From: "J. Bruce Fields" <bfields@xxxxxxxxxx>

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

===============

commit a11fcce1544df08c723d950ff0edef3adac40405 upstream.

If the entire operation fails then there's nothing to encode.
