sched/debug: Dump domains' level
Knowing domain's level exactly can be useful when setting
relax_domain_level or cpuset.sched_relax_domain_level
Usage:
cat /debug/sched/domains/cpu0/domain1/level
to dump cpu0 domain1's level.
SDM macro is not used because sd->level is 'int' and
it would hide the type mismatch between 'int' and 'u32'.
