wpa_supplicant: Issue with long scan times on startup.

When you have lots of stations, the initial scan time logic
goes a bit haywire, causing long delays before the initial scan
is attempted.

The patch below works better for me:

diff --git a/wpa_supplicant/wpa_supplicant.c b/wpa_supplicant/wpa_supplicant.c
index 4b8d0d0..a398bb8 100644

         wpa_s->prev_scan_wildcard = 0;

         if (wpa_supplicant_enabled_networks(wpa_s)) {
-               if (wpa_supplicant_delayed_sched_scan(wpa_s, interface_count,
+               if (wpa_supplicant_delayed_sched_scan(wpa_s, interface_count % 3,
-                       wpa_supplicant_req_scan(wpa_s, interface_count,
+                       wpa_supplicant_req_scan(wpa_s, interface_count % 3,
         } else

Any interest in pushing something like this upstream?
