mac80211: Fix incorrectly named last_hop_metric variable in mesh_rx_path_sel_frame
The last hop metric should refer to link cost (this is how
hwmp_route_info_get uses it for example). But in mesh_rx_path_sel_frame
we are not dealing with link cost but with the total cost to the origin
of a PREQ or PREP.
