wifi: mac80211: fix MLE defragmentation

If either reconf or EPCS multi-link element (MLE) is contained in a non-transmitted profile, the defragmentation routine is called with a pointer to the defragmented copy, but the original elements.

This is incorrect for two reasons:

  • if the original defragmentation was needed, it will not find the correct data
  • if the original frame is at a higher address, the parsing will potentially overrun the heap data (though given the layout of the buffers, only into the new defragmentation buffer, and then it has to stop and fail once that's filled with copied data.

Fix it by tracking the container along with the pointer and in doing so also unify the two almost identical defragmentation routines.
