wifi: iwlwifi: mvm: only clients can be 20MHz-only 

Since only clients to an AP can be 20MHz-only STAs, adjust the
code to not make the use of EHT capabilities depend on only the
bandwidth, but also the type of interface.

Fixes: 701404f109 ("wifi: iwlwifi: rs: add support for parsing max MCS per NSS/BW in 11be")
