4.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Kirill Tkhai <ktkhai@xxxxxxxxxxxxx>
commit 109728ccc5933151c68d1106e4065478a487a323 upstream.
The above error path returns with page unlocked, so this place seems also
to behave the same.
Fixes: f8dbdf81821b ("fuse: rework fuse_readpages()")
