i965: Fix brw_gs_prog_data_compare to actually check field members.

Browse source 
&a and &b are the address of the local stack variables, not the actual
structures.  Instead of comparing the fields of a and b, we compared
...some stack memory.

Not a candidate for stable since GS code doesn't exist in 9.2.
