As the Multi-Link element might be fragmented, add support for reassembling a fragmented element. To simplify memory management logic, extend 'struct ieee802_11_elems' to hold a scratch buffer, which is used for the defragmentation. Once an element is reconstructed in the scratch area, point the corresponding element pointer to it. Currently only defragmentation of Multi-Link element and the contained per-STA profile subelement is supported.
