wifi: mac80211: Allow HT Action frame processing on 6 GHz when HE is supported

Management frames on 6 GHz do not include HT Capabilities, causing HT
Action frames to be dropped in ieee80211_rx_h_action(). 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.
