[PATCH AUTOSEL 6.7 28/58] wifi: mac80211: initialize SMPS mode correctly

[Sasha Levin]

From: Johannes Berg <johannes.berg@xxxxxxxxx>

[ Upstream commit 86b2dac224f963be92634a878888222e1e938f48 ]

The SMPS mode is currently re-initialized too late, since
ieee80211_prep_channel() can be called again after we've
already done ieee80211_setup_assoc_link(), in case there's
some override of the channel configuration. Fix this.
