Subject: [PATCH 1/2] sched/topology: loop properly when clearing flags

Fixed commit introduced sched_group::flags and a loop that was supposed
to clear groups' flags if the child sched_domain was deleted.  The
iterating part was missing.

Fixes: 16d364ba6ef2 ("sched/topology: Introduce sched_group::flags")
