[PATCH 5.19 16/48] wifi: iwlwifi: dont spam logs with NSS>2 messages

[ Upstream commit 4d8421f2dd88583cc7a4d6c2a5532c35e816a52a ]

I get a log line like this every 4 seconds when connected to my AP:

[15650.221468] iwlwifi 0000:09:00.0: Got NSS = 4 - trimming to 2

Looking at the code, this seems to be related to a hardware limitation,
and there's nothing to be done. In an effort to keep my dmesg
manageable, downgrade this error to "debug" rather than "info".
