[PATCH] suggestion : flush outputs in wpa_printf

[Annie Rota]

Hi all,
In order to improve interprocess readability between wpa_supplicant and
clients of the control interface,
I propose to fflush the outputs of wpa_printf more often (especially
stdout).

Regards,

          if (out_file) {
              vfprintf(out_file, fmt, ap);
              fprintf(out_file, "\n");
+             fflush(out_file),
          } else {
  #endif /* CONFIG_DEBUG_FILE */
          vprintf(fmt, ap);
          printf("\n");
+         fflush(stdout);
  #ifdef CONFIG_DEBUG_FILE
          }
  #endif /* CONFIG_DEBUG_FILE */
