virtio: Revert "virtio: find_vqs() add arg sizes"

2022-08-16T05:40:24Z

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.

This reverts commit cdb44806fca2d0ad29ca644cbf1505433902ee0c: the legacy path is wrong and in fact can not support the proposed API since for a legacy device we never communicate the vq size to the hypervisor.
