[PATCH]Fix for macro in agp.h

[PATCH]Fix for macro in agp.h

Hello

Here is a $0.02 patch that fixes the dirty 'A_IDX*' macros in agp.h. 
These were referring to a variable 'i' that is local to the routine 
where these macros are called (namely 'agp_generic_create_gatt_table' in 
'agpgart_be.c').
The patch is against 2.4.17
Thanks Phil Brown for pointing this one...

Best regards
