virtio: Revert "virtio: find_vqs() add arg sizes"
This reverts commit a10fba0377145fccefea4dc4dd5915b7ed87e546: the
proposed API isn't supported on all transports but no
effort was made to address this.
It might not be hard to fix if we want to: maybe just
rename size to size_hint and make sure legacy
transports ignore the hint.
But it's not sure what the benefit is in any case, so
let's drop it.
Fixes: a10fba037714 ("virtio: find_vqs() add arg sizes")
