i965: Fix glColorPointer(GL_FIXED)
When a gl_client_array is created with glColorPointer,
gl_client_array::Normalized is true. This caused the translation from the
gl_client_array's type to a BRW_SURFACEFORMAT to assertion fail.
Fixes the spinning cube's color in Android 4.2's ApiDemos.apk,
"Graphics > OpenGL ES".
Fixes assertion failure in mesa-demos/src/egl/opengles1/tri_x11 on Haswell
and Ivybridge:
brw_draw_upload.c:287: get_surface_type: Assertion `0' failed.
No Piglit regressions on Haswell.
Note: This is a candidate for the 9.1 branch.
