In the error handling of s3c_camif_probe, s3c_camif_unregister_subdev
may be executed twice, one is from camif_unregister_media_entities.
Although there is sanity check about the registration status,
it is not good to call s3c_camif_unregister_subdev twice in the error
handling code.
Fix this by moving s3c_camif_unregister_subdev out of
camif_unregister_media_entities, and add a s3c_camif_unregister_subdev
in the s3c_camif_remove.
