drm/radeon: Take all modeset locks for DP MST hotplug
Similar with the i915 take all modeset locks for mst hotplug. This is
needed to make sure radeon holds both mode_config.mutex and
mode_config.connection_mutex when updating the connector_list, which
is the new (interim) locking regime we want for that.
