mesa: get correct src address for transferOps

When texstore_rgba() takes the path that doesn't handle
transferOps it was correctly calling _mesa_image_address()
to apply any pixel store unpack setting to the starting src
address. This was missing from the transferOps path so we add it
in this patch.
