Shaohua Li e9ce335df5 cfq-iosched: fix a kbuild regression ...

Alex Shi reported a kbuild regression which is about 10% performance lost.
He bisected to this commit: 3dde36ddea.
The reason is cfqq_close() can't find close cooperator. Restoring
cfq_rq_close()'s threshold to original value makes the regression go away.

Since for_preempt parameter isn't used anymore, this patch deletes it.
