Add new management function to struct timer_list


Make sure that del_timer succeeds and removes an entry from the list. Currently
sending the LOCATION UPDATING REJECT from within the timer will not remove the
list element as ->active gets set to 0 in the timer updating before calling the
callback. Fix the segfault and allow the timer to be removed from within its
own callback.
