drm/display: bridge_connector: Use cached connector status in .get_modes()
Replace the active drm_bridge_connector_detect() call in get_modes()
with a read of the already-cached connector->status.
The .get_modes() callback is only invoked from
drm_helper_probe_single_connector_modes(), which has already retrieved
the connector status. Calling detect again is redundant and triggers a
duplicate hotplug event. This is also a prerequisite for switching to
the .detect_ctx() hook, which requires a drm_modeset_acquire_ctx not
available in the .get_modes() path.
