vm-virtio: block: Ensure that VIRTIO_BLK_T_FLUSH requests actually sync
The implementation of this virtio block (and vhost-user block) command called a function that was a no-op on Linux. Use the same function as virtio-pmem to ensure that data is not lost when the guest asks for it to be flused to disk. Fixes: #399 Signed-off-by: Rob Bradford <robert.bradford@intel.com>
