[INET]: Small possible memory leak in FIB rules
This patch fixes a small memory leak. Default fib rules can be deleted by
the user if the rule does not carry FIB_RULE_PERMANENT flag, f.e. by
ip rule flush
Such a rule will not be freed as the ref-counter has 2 on start and becomes
clearly unreachable after removal.
