MFC r184720:

  Fix a bug introduced with r182851 (r201653 in stable/7) splitting
  tcp_mss() into tcp_mss() and tcp_mss_update() so that tcp_mtudisc()
  could re-use the same code.

  In case we return early and got a metricptr to pass the hostcache
  info back to the caller we need to initialize the data to a defined
  state (zero it) as tcp_hc_get() would do if there was no hit.
  Without that the caller would check on random stack garbage which
  could lead to undefined results.

  This only affected tcp_mss() if there was no routing entry for the peer,
  tcp_mtudisc() was not affected.
