[PATCH 1/3] [media] coda: Call v4l2_device_unregister() from a single location

[Fabio Estevam <festevam@gmail.com>]

From: Fabio Estevam <fabio.estevam@freescale.com>

Instead of calling v4l2_device_unregister() in multiple locations within the
error paths, let's call it from a single location to make the error handling
simpler.
