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.

Move virtio_synchronize_cbs from virtio pci to virtio_reset_device
fixing this for all transports that implement synchronize_cbs().

NB: transports without synchronize_cbs are probably still broken.
