wifi: mt76: mt7925: populate EHT 320MHz MCS map in sta_rec

Browse Source 
The sta_rec_eht structure has a mcs_map_bw320 field, and the channel
width mapping includes NL80211_CHAN_WIDTH_320, but the 320MHz MCS/NSS
map was never copied from the station's EHT capabilities to the MCU TLV.
This prevents negotiation of 320MHz channel width even when both the
hardware and firmware advertise support for it.

Add the missing memcpy for the 320MHz MCS map, matching the existing
pattern for BW20, BW80, and BW160.
