Tearing down the ring buffers across resume is overkill, risks unnecessary failure and increases fragmentation. After failure, since the device is still active we may end up trying to write into the dangling iomapping and trigger an oops. v2: stop_ringbuffers() was meant to call stop(ring) not cleanup(ring) during resume!
