[PATCH 02/39] drm/atomic: Convert drm_atomic_get_connector_state() to state accessor

[Maxime Ripard]

The drm_atomic_get_existing_connector_state() looks up if a connector
state was already allocated in the global state before trying to
allocate a new one.

It does so using a hand-crafted version of
drm_atomic_get_existing_connector_state(), so let's convert to that
helper, even though it's currently deprecated.
