i965: Fix border color on Ironlake.

Ironlake appears to check our pointer against the General State Base
Address upper bound, rather than ignoring the zero bound as it ought.

Unfortunately, since we leave GSBA set to zero, there is no logical
upper bound.  Set it to the maximum possible value, which should work
since our virtual addresses only go up to 2GB.

+94 piglits.

NOTE: This is a candidate for stable release branches.
