fs/xfs/quota: Add missing mutex_unlock
Add a mutex_unlock missing on the error path. The use of this lock
is balanced elsewhere in the file.
The semantic match that finds this problem is as follows:
(http://coccinelle.lip6.fr/)
// <smpl>
@@
expression E1;
@@
* mutex_lock(E1,...);
<+... when != E1
if (...) {
... when != E1
* return ...;
}
...+>
* mutex_unlock(E1,...);
// </smpl>
