KVM: arm64: Allow get_pkvm_hyp_vm() to take a reference to a dying VM

Now that completion of the teardown path requires a refcount of zero for
the target VM, we can allow get_pkvm_hyp_vm() to take a reference on a
dying VM, which is necessary to unshare pages with a non-protected VM
during the teardown process itself.

Note that vCPUs belonging to a dying VM cannot be loaded and pages can
only be reclaimed from a protected VM (via
__pkvm_reclaim_dying_guest_page()) if the target VM is in the dying
state.
