media: v4l2-ctrls: improve media_request_(un)lock_for_update The request reference count was decreased again once a reference to the request object was taken. Postpone this until we finished using the object. In theory I think it is possible that the request_fd can be closed by the application from another thread. In that case when request_put is called the whole request would be freed. It's highly unlikely, but let's just be safe and fix this potential race condition.
