V4L/DVB: drivers/video/omap2/displays: add missing mutex_unlock
Add a mutex_unlock missing on the error paths. The use of the mutex 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>
