kernel: fix livelock in rebalance (thanks Richard Miller)
Once a second rebalance() is called on cpu0 to adjust priorities,
so cpu-bound processes won't lock others out. However it was only
adjusting processes which were running on cpu0. This was observed
to lead to livelock, eg when a higher-priority process spin-waits
for a lock held by a lower priority one.
