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

drm_atomic_helper_wait_for_dependencies() is the final part of a commit
and signals it completion. It takes the drm_atomic_state being committed
as a parameter.

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