i965: Use tex_mocs instead of rb_mocs for GL images.
Fixes a 10-20% performance regression in OglCSDof caused by commit
5a8c89038abab0184ea72664ab390ec6ca58b4d6, which made images (in the
image load/store sense) use BDW_MOCS_PTE instead of BDW_MOCS_WB.
This seems sketchy, as the default PTE value is supposed to be
WB LLC eLLC, which is the same as our MOCS WB setting. It's only
supposed to change when using a surface for display, which won't
ever happen for images. Something may be wrong in the kernel...
