[PATCH] drm/fsl-dcu: use drm_mode_config_cleanup on initialization errors

[Stefan Agner]

Commit 7566e247672d ("drm/fsl-dcu: handle initialization errors properly")
introduced error handling during initialization, but with a wrong cleanup
order.

Replace the error handling with the generic cleanup function
drm_mode_config_cleanup.
