WPS: Disable AP PIN after 10 consecutive failures

While the exponential increase in the lockout period provides an
efficient mitigation mechanism against brute force attacks, this
additional trigger to enter indefinite lockout period (cleared by
restarting hostapd) will limit attacks even further by giving maximum of
10 attempts (without authorized user action) even in a very long term
attack.
