KVM: arm/arm64: Fix userspace_irqchip_in_use counting
We were not decrementing the static key count in the right location.
kvm_arch_vcpu_destroy() is only called to clean up after a failed
VCPU create attempt, whereas kvm_arch_vcpu_free() is called on teardown
of the VM as well. Move the static key decrement call to
kvm_arch_vcpu_free().
