Hi Tetsuo,

quoted

"grep -FrB1 'del_timer' drivers/ | grep -FA1 '.function)'" says that
currently there are 28 locations which call del_timer[_sync]() only if
that timer's function field was initialized (because timer_setup()
sets that timer's function field). Therefore, let's use same approach here.

Thanks for the change, it look cleaner than my re-work;
