wifi: mt76: fix HE DCM max-RU capability encoding

Browse Source 
sta_rec_he.dcm_rx_max_nss was assigned twice: the second assignment,
sourced from HE PHY capability byte 8 (DCM max RU), overwrote the RX-NSS
value and left dcm_max_ru at zero. Every associated HE station advertising
DCM support was configured in firmware with a wrong dcm_rx_max_nss and a
zero dcm_max_ru. Store the DCM max-RU value in dcm_max_ru as intended.

The same copy-paste error existed in both the shared connac2 path and the
mt7915 path.

Fixes: c336318f57a9 ("mt76: mt7915: add HE capabilities support for peers")
Fixes: 67aa27431c7f ("mt76: mt7921: rely on mt76_connac_mcu common library")
