From: Jérôme Pouiller <jerome.pouiller@xxxxxxxxxx>
Since wfx_tx_get_raw_link_id() return an unsigned, it makes no sense to
return a negative value. "15" is a better value since it is used by
firmware for stations that have not yet associated link-ids.
Note that this should never happens since driver set max_ap_assoc_sta
to 14.
Fixes: 9bca45f3d692 ("staging: wfx: allow to send 802.11 frames")
