drm/atomic-helper: Simplify commit tracking locking
The crtc->commit_lock only protects commit_list and commit_entry. If we chase the pointer from the drm_atomic_state update structure, then we don't need any locks (since we hold a reference already). Simplify the locking accordingly. Noticed while reviewing a patch from Boris.
