This may be a bit too restrictive conditions. While 4-digit PINs are not
very commonly used, I think that they would be allowed for P2P use
cases. As such, I don't think I can apply this patch in its current
form. In addition, user-generated 8-digit PINs are not required to
include a checksum digit, so the use of wps_pin_valid() may not actually
be valid for some use cases.
I would be fine with a change that verifies that the PIN value is either
a 4-digit or 8-digit number, but I'm not sure whether we can make this
command any more restrictive than that. Please note that the separate
wps_check_pin command was added for this same reason instead of making
wps_pin command validate the PIN values.
