wifi: iwlwifi: mvm: limit EHT 320 MHz MCS for STEP URM
If the STEP (the interface between MAC and PHY) is in URM
(a lower speed mode) then we cannot use 320 MHz MCS > 9.
Therefore, limit the MCS in our capabilities in this case.
Note that this also limits the TX/rate scaling since that
takes both TX and RX capabilities into account.
