Kairui Song 74363ec674 zram: fix uninitialized ZRAM not releasing backing device ... Setting backing device is done before ZRAM initialization. If we set the backing device, then remove the ZRAM module without initializing the device, the backing device reference will be leaked and the device will be hold forever. Fix this by always reset the ZRAM fully on rmmod or reset store.
