[PATCH v3 4/8] KVM: arm/arm64: vgic: Reset base address on kvm_vgic_dist_destroy()

[Eric Auger <eric.auger@redhat.com>]

On vgic_dist_destroy(), the addresses are not reset. However for
kvm selftest purpose this would allow to continue the test execution
even after a failure when running KVM_RUN. So let's reset the
base addresses.

v1 -> v2:
- use dist-> in the else and add braces
