Subject: [PATCH] Initialize the scan total in nodediscover register

register_endpoint primes current but not total, so a first response
without a count field goes straight to

  UnboundLocalError: local variable 'total' referenced before assignment

on the elif.  Start at zero, which skips the progress line until the
server does report a count.
