i965: Fix texture buffer rendering after a whole buffer replacement.
If glBufferData(), glBufferSubData(0, obj->Size), or similar happens, we
get a new drm_intel_bo for the buffer object, and thus need to re-upload
texture buffer state so we point at the new data.
Fixes the new piglit GL_ARB_texture_buffer_object/data-sync
