[Mesa-dev] [PATCH 1/3] i965: solve cubemap negative x/y/z faces buffer offset issue in dEQP.

Add the miptree level/slice x/y_offset when count the surface offset
in brw_emit_surface_state. The surface offset has two parts, one is
from mt->offset, which should be 32 aligned in width/height for tiled
buffer; another is from mt->level[current_level].slice[current_slice].
x/y_offset.

This fix will solve 12 deqp failure
dEQP-EGL.functional.image.create.gles2_cubemap_negative_*_texture
