virtio-blk: store opt_io_size with correct size
The width of opt_io_size in virtio_blk_config is 32bit. However, it's
written with virtio_stw_p; this may result in value truncation, and on
big-endian systems with legacy virtio in completely bogus readings in
the guest.
Use the appropriate accessor to store it.
