drm/atomic-helper: Change parameter name of drm_atomic_helper_commit_tail_rpm()

drm_atomic_helper_commit_tail_rpm() is the final part of an atomic
commit, and is given the state being committed as a parameter.

However, that parameter is named old_state, but documented as the "new
modeset state" which is all super confusing.

Let's rename that parameter to state.
