Revert "mac80211: allow using AP_LINK_PS with mac80211-generated TIM IE"
This reverts commit c68df2e7be0c1238ea3c281fd744a204ef3b15a0. __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 essential AP mode powersave functionality.
