m_config: remove change callback before unintialization
We don't want m_config uninitialization to call random change callbacks. This happens at the end of mp_destroy(), when almost everything else is already destroyed, and the change callbacks would probably trigger UB all over the place. The change callbacks could be trigger by m_config_restore_backups(), which is just used as a cheap way to free the remaining state. The worst is that this depends on which options may still have been part of this "backup" state, which depends on user input. Probably never a practical problem, since the backup state is most likely guaranteed to be empty before uninit is performed, but still.
