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

drm_atomic_helper_commit_tail() is the final part of an atomic commit,
and is given a parameter with the drm_atomic_state being committed.

However, that parameter name is called (and documented) as old_state,
which is pretty confusing. Let's rename that variable as state.
