WNM: Remove unused age parameter for neighbor comparison

Browse source 
compare_scan_neighbor_results() was taking an age parameter to check
whether the BSS has been seen recently. This was used historically in a
codepath when no new scan was done. However, the logic was changed in
commit 20ed289a78 ("WNM: Clean up old scan data processing") and the
parameter is not used at all anymore as it is replaced by a different
logic. Remove it.
