[media] MEDIA: ttusbir, fix double free



rc_unregister_device already calls rc_free_device to free the passed
device. But in one of ttusbir's probe fail paths, we call
rc_unregister_device _and_ rc_free_device. This is wrong and results
in a double free.
Instead, set rc to NULL resulting in rc_free_device being a noop.
