i965: Clean up error handling for context creation.
The intel_screen.c used to be a dispatch to one of 3 driver functions, but was down to 1, so it was kind of a waste. In addition, it was trying to free all of the data that might have been partially freed in the kernel 3.6 check (which comes after intelInitContext, and thus might have had driverPrivate set and result in intelDestroyContext() doing work on the freed data). By moving the driverPrivate setup earlier, we can use intelDestroyContext() consistently and avoid such problems in the future. v2: Adjust the prototype of brwCreateContext to use the proper enum (fixing a compiler warning in some builds) Reviewed-by: Kenneth Graunke <kenneth@whitecape.org> (v1)
