drm/mediatek: Fix pdev reference leak in mtk_drm_bind()
When the device is not the mmsys master, mtk_drm_bind() returns early
after taking a reference on the disp-mutex device via
of_find_device_by_node(), without ever dropping it: mtk_drm_unbind()
only puts mutex_dev for the master. Drop the reference before returning
from the non-master path.
