drm/ast: Fix double lock at PM resume
The recent commit [3ea87855: drm/helper: lock all around force mode
restore] introduced drm_modeset_lock_all() in
drm_helper_resume_force_mode() itself, while ast driver still takes
this lock before calling it. Remove the caller side lock for avoid a
fatal deadlock.
