[ Upstream commit e02bc29b2cfa7806830d6da8b2322cddd67e8dfe ]
Our components may still be using the DRM device driver (if only to access our driver's private data), so make sure to unbind them before the final drm_dev_put.
Also release our reserved memory after component unbind instead of before to match reverse creation order.
