drm/i915/dp_mst: Fix connector initialization in intel_dp_add_mst_connector()
The connector initialization in intel_dp_add_mst_connector() depends on
the device pointer in connector to be valid, at least by connector
debug printing. The device pointer is initialized by drm_connector_init(),
however that function also exposes the connector to in-kernel users,
which can't be done before the connector is fully initialized. For now
make sure the device pointer is valid before it's used, until a
follow-up change moving this to DRM core.
This issue was revealed by the commit in the Fixes: line below, before
which the above debug printing checked and handled a NULL device pointer
gracefully in DRM core.
