These options are deprecated since at least two releases, and nobody complained. Time to remove them now.

[libvirt] [PATCH] vl.c deprecate incorrect CPUs topology
by Igor Mammedov 27 Aug '18

-smp [cpus],sockets/cores/threads[,maxcpus] should describe topology so that total number of logical CPUs [sockets * cores * threads] would be equal to [maxcpus], however historically we didn't have such check in QEMU and it is possible to start VM with an invalid topology.
