arm/arm64: KVM: Don't allow creating VCPUs after vgic_initialized
commit 716139df2517fbc3f2306dbe8eba0fa88dca0189 upstream.
When the vgic initializes its internal state it does so based on the
number of VCPUs available at the time. If we allow KVM to create more
VCPUs after the VGIC has been initialized, we are likely to error out in
unfortunate ways later, perform buffer overflows etc.
