i965: Fix repeated usage of rectangle texture coordinate scaling.

Previously, we set up new entries in the params[] array on every access
of a rectangle texture.  Unfortunately, we only reserve space for
(2 * MaxTextureImageUnits) extra entries, so programs which accessed
rectangle textures more times than that would write off the end of the
array and likely crash.

We don't really have a decent mapping between the index returned by
_mesa_add_state_reference and our index into the params array, so we
have to manually search for it.
