wifi: mac80211: constify ieee80211_ie_build_{he,eht}_oper() chandef

The chandef parameter passed to ieee80211_ie_build_he_oper() and
ieee80211_ie_build_eht_oper is read-only. Since it is never modified,
add the const qualifier to this parameter. This makes these consistent
with ieee80211_ie_build_ht_oper() and ieee80211_ie_build_vht_oper().
