st/mesa: simplify lastLevel determination in st_finalize_texture

This fixes shader images where we always bind stObj->pt and not individual
gl_texture_images.

Roughly based on i965 commit 845ad2667ab2466752f06ea30bdb9c837116c308
which does a similar thing but for a different reason.

This fixes GL CTS assertion failures introduced by Ilia.
