drm/bridge: Change parameter name of drm_atomic_bridge_chain_post_disable()

drm_atomic_bridge_chain_post_disable() disables all bridges affected by
a new 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.
