[PATCH 05/16] WNM: Remove unused age parameter for neighbor comparison

[benjamin at sipsolutions.net]

From: Benjamin Berg <benjamin.berg at intel.com>

compare_scan_neighbor_results was taking an age paramter 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 20ed289a785c ("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.
