Small cleanup in hostapd_config

[Sebastien Decugis]

Hello,

I think that the "radius" pointer in the structure hostapd_config is
never used; when the configuration is parsed the related data is stored
in hostapd_bss_config's "radius" var.

Here is a patch for this change:

--- a/hostapd/config.h
+++ b/hostapd/config.h
@@ -323,7 +323,6 @@ typedef enum {
  */
 struct hostapd_config {
 	struct hostapd_bss_config *bss, *last_bss;
-	struct hostapd_radius_servers *radius;
 	size_t num_bss;
 
 	u16 beacon_int;

I applied this patch and compiled hostapd without any problem; please
let me know if I missed some other place where the field could be
referenced.

Best regards,
Sebastien.
