virtio-blk: support variable block size
Current code only works with 512 bytes read.
Moreover, Qemu ignores the guest set features request. In the set
features request SLOF indicates to qemu that it is not support
VIRTIO_BLK_F_BLK_SIZE feature. Code in qemu suggests that virtio-blk
is not implementing set_guest_feature.
