The current logic checks only ht_cap.ht_supported, which fails for 6 GHz radios that support only HE and EHT. Update the condition to also allow HT Action frame processing when he_cap.has_he is true. This enables support for HE dynamic SM power save as defined in IEEE Std 802.11ax-2021, section 26.14.4.
