[PATCH v8] virtio_blk: add discard and write zeroes support
..._BLK_T_OUT), since the read/write commands do
not specify a length explicitly; length is implied by the length of
the data buffer as defined by the virtio descriptor, but a Write
Zeroes command does not require a data buffer. At best, this could be
a separate command mirroring the layout of struct virtio_blk_req but
with data replaced with a length field; I'm not sure that buys much in
the way of consistency.
