[RADIATOR] [Patch] avoid warning on missing User-Name

[Roland Rosenfeld]

Hi,

I noticed the following issue with Radiator 4.22:
On accounting A10 CGN gateway, there is the User-Name field missing in
the accounting records.  This results in Radius/Client.pm line 777
warning, that it tries to split an uninitialized variable.

The following patch works around this issue, maybe this helps someone
with the same setup.
