[RFC PATCH 2/6] workqueue: remove redundant timer_stats_timer_set_start_info()

[Yong Zhang]

From: Yong Zhang <yong.zhang@xxxxxxxxxxxxx>

No need to call timer_stats_timer_set_start_info() explicitly,
add_timer_on() and add_timer() have done the right job.

After this change, we can move timer_stats_timer_*_start_info()
from include/linux/timer.h to kernel/timer.c. Outsider should not
see those functions.
