From: Benjamin Berg <benjamin.berg@xxxxxxxxx>
When fragmenting the ML per STA profile, the element ID should be
IEEE80211_MLE_SUBELEM_PER_STA_PROFILE rather than WLAN_EID_FRAGMENT.
Change the helper function to take the to be used element ID and pass
the appropriate value for each of the fragmentation levels.
Fixes: 81151ce462e5 ("wifi: mac80211: support MLO authentication/association with one link")
