list_nets and facts commands from virt_net do not work as listed in examples

SUMMARY

Both examples using list_nets and facts return with error: missing required arguments: name Specifying a name makes the example work, but these commands become quite useless.

Seems to be something simple to fix but I am not familiar with Ansible development. I believe the problem is related to line 605 of virt_net.py, but not sure.
