The handling of per-device mappings introduced in commit86f7ef7731("media: uvcvideo: Add support for per-device control mapping overrides") overwrote the mapping variable after it was initialized and before it was used, leading to usage of an invalid pointer for devices with per-device mappings. Fix it.
