This reverts commit 99e8927d8a4da8eb8a8a5904dc13a3156be8e7c0:
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: 99e8927d8a4d ("virtio_vdpa: support the arg sizes of find_vqs()")
