Jens Axboe 5d7f5ce151 cfq-iosched: don't call wbt_disable_default() with IRQs disabled ...

wbt_disable_default() calls del_timer_sync() to wait for the wbt
timer to finish before disabling throttling. We can't do this with
IRQs disable. This fixes a lockdep splat on boot, if non-root
cgroups are used.
