Subject: [PATCH] Revert "mac80211: allow using AP_LINK_PS with
mac80211-generated TIM IE"
This reverts commit c68df2e7be0c1238ea3c281fd744a204ef3b15a0.
Commit c68df2e7be0c ("mac80211: allow using AP_LINK_PS with
mac80211-generated TIM IE") introduced a logic error, where
__sta_info_recalc_tim turns into a no-op if local->ops->set_tim is not
set. This prevents the beacon TIM bit from being set for all drivers
that do not implement this op (almost all of them), thus thoroughly
