A compatible version (3.2.4) should has been pushed out to the stable repositories so running sudo dnf upgrade should pull it in (unless you've never installed it in the first place, in which case you should run sudo dnf install qubes-kernel-vm-support instead). Once you've installed the package, try compiling one of those kernels again and it should work.
