sched/topology: Propagate SMT flags when removing degenerate domain

When a degenerate cluster domain for core with SMT CPUs is removed,
the SD_SHARE_CPUCAPACITY flag in the local child sched group was not
propagated to the new parent.  We need this flag to properly determine
whether the local sched group is SMT.  Set the flag in the local
child sched group of the new parent sched domain.
