[PATCH] trivial: fix documentation regarding default io scheduler

[Rogério Brito]

The current Kconfig.iosched documentation says that the default I/O
scheduler is the CFQ scheduler, but the default, if nothing is changed,
is the anticipatory scheduler.

This patch fixes the documentation.

So the default is, indeed, CFQ.
