[JDEV] Patch for crash in mod_groups

[Nathan Sharp]

I found another crash in mod_groups in 1.4.2.  This was due to the code trying to free 
an xmlnode which had never been initialized.  It happens on the browse-set callback 
when the incoming packet does not have a proper <user> tag formed.  Here is a patch 
which fixes it.  This patch should be applied on top of the other patch I submitted 
here a few weeks ago.
