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

drm_atomic_helper_modeset_disables() disables all the outputs affected
by a commit. 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.
