[PATCH v3 01/12] KVM: arm/arm64: Set dist->spis to NULL after kfree

in case kvm_vgic_map_resources() fails, typically if the vgic distributor is not defined, __kvm_vgic_destroy will be called several times. Indeed kvm_vgic_map_resources() is called on first vcpu run. As a result dist->spis is freeed more than once and on the second time it causes a "kernel BUG at
