Subject[07/26] drm/i915: Fix object refcount leak on mmappable size limit error path.
3.1-stable review patch.  If anyone has any objections, please let me know.

------------------
From: Eric Anholt <eric@anholt.net>

commit 14660ccd599dc7bd6ecef17408bd76dc853f9b77 upstream.

I've been seeing memory leaks on my system in the form of large
(300-400MB) GEM objects created by now-dead processes laying around
clogging up memory. I usually notice when it gets to about 1.2GB of
them. Hopefully this clears up the issue, but I just found this bug
by inspection.
