Subject: [PATCH 3.11 093/182] nfsd4: leave reply buffer space for failed setattr

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

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

From: "J. Bruce Fields" <bfields@...hat.com>

commit 04819bf6449094e62cebaf5199d85d68d711e667 upstream.

This fixes an ommission from 18032ca062e621e15683cb61c066ef3dc5414a7b
"NFSD: Server implementation of MAC Labeling", which increased the size
of the setattr error reply without increasing COMPOUND_ERR_SLACK_SPACE.
