Running the KVM selftests results in these messages being dumped
in the kernel console:

[  188.051073] kvm [469]: VGIC redist and dist frames overlap
[  188.056820] kvm [469]: VGIC redist and dist frames overlap
[  188.076199] kvm [469]: VGIC redist and dist frames overlap

Being amle to trigger this from userspace is definitely not on,
so demote these warnings to kvm_debug().
