[0/3] KVM: arm64: Handle KVM_REQ_VM_DEAD in vgic_init test

Message

Mark reported that df5fd75ee305 ("KVM: arm64: Don't eagerly
teardown the vgic on init error") causes vgic_init test
assertion failure. This is due to the fact that now an
incomplete vgic setup causes a KVM_REQ_VM_DEAD request to
be sent. vgic_init test checks such kind of incomplete setups.
As a consequence some KVM IOCTL's fail on the clean up path
(kvm_vm_free) and cause assertion failures in the test.

This series fixes that by checking the VM state and avoid to
call KVM IOCTL's after the occcurence of such failure.

Best regards

Eric
