[gdm-list] willing_output double free

[Bruno Cesar Ribas <ribas c3sl ufpr br>]

Hi,

Since gdm 2.20 it is not possible to set a Xwilling script to show a
customized message at gdm chooser.

This happens because there's a double free at function
gdm_xdmcp_send_willing

The double free error happens when gdm is going to show the xwilling message
for the second time.

Here are the pacth to fix it under gdm 2.24 and 2.25.1
