sched: correct SD_flags returned by tl->sd_flags()
[ Upstream commit 9b1b234bb86bcdcdb142e900d39b599185465dbb ]
During sched domain init, we check whether non-topological SD_flags are
returned by tl->sd_flags(), if found, fire a waning and correct the
violation, but the code failed to correct the violation. Correct this.
Fixes: 143e1e28cb40 ("sched: Rework sched_domain topology definition")
