virtio_ring: add a func argument 'recycle_done' to virtqueue_resize()
commit 8d6712c892019b9b9dc5c7039edd3c9d770b510b upstream.
When virtqueue_resize() has actually recycled all unused buffers,
additional work may be required in some cases. Relying solely on its
return status is fragile, so introduce a new function argument
'recycle_done', which is invoked when the recycle really occurs.
