Log: linuxkpi: Fix mod_timer and del_timer_sync mod_timer is supposed to return 1 if the modified timer was pending, which is exactly what callout_reset does so return the value after checking that it's a correct one in case the api change. del_timer_sync returns int so add a function and handle that.
