wl12xx: move ap_hlid_map into wlvif.ap
Add wlvif->links_map bitmap to represent all the links allocated for this vif. AP vif also has a sta_hlid_map bitmap, which represents the links stations connected to it (sta_hlid_bitmap is a subset of wlvif->links_map, which itself is a subset of the global wl->links_map) Signed-off-by: Eliad Peller <eliad@wizery.com> Signed-off-by: Luciano Coelho <coelho@ti.com>
