This fixes the error handling in the function vgic_v3_probe
for when calling the function kvm_register_device_ops to check
if the call to this function has returned a error code and if
so jump to the label out with goto to cleanup no longer required
resources used by the function vgic_v3_probe before returning the
error code from the call to kvm_register_device_ops to the caller
of the function vgic_v3_probe.
