Marc Zyngier e13ce009ec KVM: arm64: vgic: Force vcpu vgic teardown on vcpu destroy 
commit 02e3858f08 upstream.

When failing to create a vcpu because (for example) it has a
duplicate vcpu_id, we destroy the vcpu. Amusingly, this leaves
the redistributor registered with the KVM_MMIO bus.

This is no good, and we should properly clean the mess. Force
a teardown of the vgic vcpu interface, including the RD device
before returning to the caller.
