[PATCH v2 3/3] virtio-9p-device: switch to 32k max. transfer size

[Christian Schoenebeck <qemu_oss@crudebyte.com>]

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).
