6.6-stable review patch. If anyone has any objections, please let me know.
------------------
From: Johannes Berg <johannes.berg@xxxxxxxxx>
[ Upstream commit b1a2e5c310e063560760806d2cc5d2233c596067 ]
The firmware changed their mind, don't set the chains to zero,
instead set them to 1 as we normally would for connections to
APs that don't use MIMO.
Fixes: 2a7ce54ccc23 ("iwlwifi: mvm: honour firmware SMPS requests")
