[libvirt] [PATCH] virsh: Return false if only '--wipe-storage' is assigned when undefine a domain

For now, if only '--wipe-storage' is assigned, user can undefine a domain normally. But actually '--wipe-storage' doesn't work, this may confuse user. And since '--wipe-storage' wipes data on the removed volumes, if no removed volume storage assigned, we'd better raise an error message. Before: $ virsh undefine virt-tests-vm1 --wipe-storage Domain virt-tests-vm1 has been undefined After: $ virsh undefine virt-tests-vm1 --wipe-storage error: '--wipe-storage' needs storage volume deletion: '--stroage <string>' or '--remove-all-storage' is necessary.
