9pfs supports the new maximum virtio queue size of 32k, so let's switch the 9pfs virtio transport from 1k to 32k. This will allow a maximum 'msize' option (maximum message size) by 9p client of approximately 128M (assuming 4k page size, in practice slightly smaller, e.g. with Linux client minus 2 pages).
