cel/cel_radius: Fix wrong pointer.

The macro ADD_VENDOR_CODE defined in the cel_radius.c should use the parameter
y not the address of y.

I capture the radius UDP packet via tcpdump, and the AV pairs are not correct,
then i review the source code and compare it with cdr/cdr_radius.c. Fix it and
 it works.
