Hangyu Hua d4c8bf5635 rpmsg: Fix possible refcount leak in rpmsg_register_device_override() ...

commit d7bd416d35 upstream.

rpmsg_register_device_override need to call put_device to free vch when
driver_set_override fails.

Fix this by adding a put_device() to the error path.

Fixes: bb17d110cb ("rpmsg: Fix calling device_lock() on non-initialized device")
