From: Joonsoo Kim

There are some users of deferrable timer. Because of lacking of
handy initializer, they should initialize deferrable timer fumblingly.
We might do better with new setup_timer_deferrable() macro.
So add it.

Following patch will makes some users of init_timer_deferrable() use
this handy macro.
