it may get a bit "dirty" to achieve this, since we would need to move the
avl_delete() call into olsr_tc_unlock() before freeing memory, otherwise
the TC "hookup point" does not become locatable. - this in turn may
create all sort of yet invisible side-effects (caused by events like
main IP address change etc.).
