  virtio-blk: Add blk_drain() to virtio_blk_device_unrealize()

QEMU does not wait for completed I/O requests, assuming that the guest
driver will reset the device before calling unrealize(). This does not
happen on Windows, and QEMU crashes in virtio_notify(), getting the
result of a completed I/O request on hot-unplugged device.
