virtio-blk: use larger default request size

Bump default from 8 to 64 blocks.  Using 8 by default leads
to requests being splitted on qemu, which slows down boot.

Some (temporary) debug logging added showed that almost all
requests on a standard fedora install are less than 64 blocks,
so that should bring us back to 1.15 performance levels.
