KVM: arm64: vgic: Free private_irqs when init fails after allocation

In the Linux kernel, the following vulnerability has been resolved:

KVM: arm64: vgic: Free private_irqs when init fails after allocation

Companion to commit 250f25367b58 ("KVM: arm64: Tear down vGIC on
failed vCPU creation"), which added the missing kvm_vgic_vcpu_destroy()
call to the kvm_share_hyp() failure path in kvm_arch_vcpu_create(). The
kvm_vgic_vcpu_init() failure path immediately above it has the same
shape and still needs the same cleanup.

Call kvm_vgic_vcpu_destroy() when kvm_vgic_vcpu_init() fails so private
IRQs allocated before a redistributor iodev registration failure are
released before the failed vCPU is freed.
