[PATCH] IPMI: use schedule in kthread



Corey Minyard <minyard@acm.org>

The kthread used to speed up polling for IPMI was using udelay in its
busy-wait polling loop when the lower-level state machine told it to do a
short delay.  This just used CPU and didn't help scheduling, thus causing
bad problems with other tasks.  Call schedule() instead.
