5add4101626b23c11f073630770896465d9cc8f3 ('WPS: Use shorter authentication
timeout during no-SelReg iteration') introduced the shorter timeout for PIN
A shorter timeout in PBC mode is useful for P2P. This allows authentication
retries after lost packages, before the group formation times out.

I'm not sure if this is the correct fix. I want to avoid the 70 seconds
timeout for P2P and this seemed the cleanest way to achieve this.
