The information needed to delete ip rules associated
with fips is held in memory between add and remove so
a restart of the l3-agent results in any fips that
existed before the restart having their ip rules
persist after the fips are removed. This patch
enures that an agent restart reloads this information
so that ip rules associated with a fip are correctly
removed when the fip is removed.
