timer: Make try_to_del_timer_sync() the same on SMP and UP
On UP try_to_del_timer_sync() is mapped to del_timer() which does not
take the running timer callback into account, so it has different
semantics.
Remove the SMP dependency of try_to_del_timer_sync() by using
base->running_timer in the UP case as well.
[ tglx: Removed set_running_timer() inline and tweaked the changelog ]
