Fix infinite recursion deadlock on netns cleanup

Browse Source 
When, for some reason, the neutron netns agent is misconfigured and is
producing errors, this infinite recursion is generating a deadlock on
cpu usage since it repeats with no interval. This fix adds some shorter
sleeps to work around it.
