KVM: GIC: Fix memory leak due to calling kvm_init_irq_routing twice

kvm_irqchip_create called by kvm_init will call kvm_init_irq_routing to
initialize global capability variables. If we call kvm_init_irq_routing in
GIC realize function, previous allocated memory will leak.

Fix this by deleting the unnecessary call.
