Xevie: always initialize rep.length (bug#17394)

Browse source 
The XEvIE extension doesn't clear the rep.length field for any reply but
the version check. Hence, if there is junk data in it and that is sent
to the client, it hangs.

X.Org bug#17394 (http://bugs.freedesktop.org/show_bug.cgi?id=17394)
