[PATCH 13/12] sched: remove debug check

[Peter Zijlstra]

Since you're running into this warning and not seeing any obvious ill
side-effects (you'd see some serious starvation issues), please stick
this patch in for now.

I can't seem to convince myself if its a real problem or not, and how it
could possibly happen, but my brain is giving up for today.
