Subject[PATCH 3.16 144/305] xfrm: Fix bucket count reported to userspace
3.16.63-rc1 review patch.  If anyone has any objections, please let me know.

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

From: Benjamin Poirier <bpoirier@suse.com>

commit ca92e173ab34a4f7fc4128bd372bd96f1af6f507 upstream.

sadhcnt is reported by `ip -s xfrm state count` as "buckets count", not the
hash mask.

Fixes: 28d8909bc790 ("[XFRM]: Export SAD info.")
