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

disable_outputs() disables all connectors and CRTCs affected by a
commit. It takes the drm_atomic_state being committed as a parameter.

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