[virt-tools-list] [PATCH virt-manager] Allow empty cpu model



If we specify cpu model and apply once, we could not specify empty
cpu model again with following error.
"Error changing VM configuration: internal error Non-empty feature
list specified without CPU model"
That is not useful to restore default cpu model.
This patch fixes above issue.
