[PATCH 5/5] sched: make fix_small_imbalance work with asymmetric packing

[Michael Neuling <mikey@neuling.org>]

With the asymmetric packing infrastructure, fix_small_imbalance is
causing idle higher threads to pull tasks off lower threads.  

This is being caused by an off-by-one error.

I'm not sure this is the right fix but without it, higher threads pull
tasks off the lower threads, then the packing pulls it back down, etc
etc and tasks bounce around constantly.
