msm: camera: Synchronize v4l2 subscribe and unsubscribe event in camera.c

If same event is unsubscribed before v4l2_event_subscribe returned,
Then function v4l2_event_subscribe have possibility use-after-free.

Serialize msm_subscribe_event and msm_unsubscribe_event to
prevent parallel invocation of v4l2_event_subscribe and
v4l2_event_unsubscribe.
