ipfilter: Remove dead code from "Virtualize ipfilter"

Browse Source 
6d8a5eacae virtualized ipfilter for VNET. A few  remnants of old
defunct code remained. Remove them. At the time it was not known if
6d8a5eacae would cause any issues. As it's been a number of years
since the conversion was done, it's certainly safe to remove the
dead code.
