media: venus: fix enc/dec destruction order

Browse Source 
We destroy mutex-es too early as they are still taken in
v4l2_fh_exit()->v4l2_event_unsubscribe()->v4l2_ctrl_find().

We should destroy mutex-es right before kfree().  Also
do not vdec_ctrl_deinit() before v4l2_fh_exit().

Fixes: 7472c1c691 ("[media] media: venus: vdec: add video decoder files")
