wifi: mac80211: fragment per STA profile correctly

[ Upstream commit d094482c9974a543851a18a1c587a7d132a81659 ]

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: 81151ce4
