qemu_validate: Allow kvm hint-dedicated on non-passthrough VMs
qemu_validate: Allow kvm hint-dedicated on non-passthrough VMs

A VM defined similar to:
  ...
  <features><kvm><hint-dedicated state='on'/></kvm></features>
  <cpu mode="host-model"/>
  ...
is currently invalid, as hint-dedicated is only allowed if cpu mode
is host-passthrough or maximum. This restriction is unnecessary, see
https://bugzilla.redhat.com/show_bug.cgi?id=1857671
