drm/i915: Allocate connector state together with the connectors
Connector states were being allocated in intel_setup_outputs() in loop
over all connectors. That meant hot-added connectors would have a NULL
state. Since the change to use a struct drm_atomic_state for the legacy
modeset, connector states are necessary for the i915 driver to function
properly, so that would lead to oopses.
v2: Fix test for intel_connector_init() success in lvds and sdvo (PRTS)
