cpuset: fix wrong calculation of relax domain level

When multiple cpusets are overlapping in their 'cpus' and hence they
form a single sched domain, the largest sched_relax_domain_level among
those should be used. But when top_cpuset's sched_load_balance is
set, its sched_relax_domain_level is used regardless other sub-cpusets'.

This patch fixes it by walking the cpuset hierarchy to find the largest
sched_relax_domain_level.
