[Serusers] avp_db_load fails with avp as source

[Greger V. Teigre]

Brett,
I have never used avpairs with sql (I use radius), but I believe the 
avp_db_load statement should be removed alltogether.  The avps_column_str 
instructs the auth module to load the value in the callscope column ON 
SUCCESSFUL AUTHENTICATION, i.e. when the user is authenticated, the avp is 
already loaded and ready to be used.
