Do not offer DHCP leases to unknown machines when using inventory_dhcp

Browse Source 
Turns out the dhcp-range option of dnsmasq does not constrain
the DHCP leases to the range specified.
When using inventory_dhcp, we specify the *exact* set of machines
that will be managed by dnsmasq via the json inventory and therefore
it should just provide IPs to those machines.
