Subject: [PATCH] rust: list: undo unintended replacement of method name

When we renamed `Opaque::raw_get` to `cast_into`, there was one
replacement that was not supposed to be there.

It does not cause an issue so far because it is inside a macro rule (the
`ListLinksSelfPtr` one) that is unused so far. However, it will start
to be used soon.

Thus fix it now.
