Add "--nvram" to virsh undefine domain when clean_nova

For the instance which has boot by uefi, we should use
virsh undefine --nvram to undefine it. Check the libvirt
version for whether it supports nvram and use new undefine
parameters since this parameters is compatible with those
instance which don't use uefi.
