[PATCH 12/30] drm/bridge/analogix/anx6345: Cleanup on errors in anx6345_bridge_attach()

[Lyude Paul]

Another drive-by fix I found when fixing DP AUX adapter across the kernel
tree - make sure we don't leak resources (and by proxy-AUX adapters) on
failures in anx6345_bridge_attach() by unrolling on errors.
