SVN rev 184720 on 2008-11-06 12:33:33Z by bz
Fix a bug introduced with r182851 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.
MFC after: 2 months (along with r182851)
