virtio: synchronize callbacks after device reset
virtio_reset_device says:
Note: this guarantees that vq callbacks are not in progress
but in practice, only virtio pci correctly synchronizes the cbs.
On other transports, a callback that is already executing, keeps running
while the driver tears down the state it uses.
Add virtio_synchronize_cbs to virtio_reset_device fixing this for all
transports that correctly implement synchronize_cbs().
