sched: Avoid division by zero
Patch a5004278f0525dcb9aa43703ef77bf371ea837cd (sched: Fix
cgroup smp fairness) introduced the possibility of a
divide-by-zero because load-balancing is not synchronized
between sched_domains.
This can cause the state of cpus to change between the first
and second loop over the sched domain in tg_shares_up().
