rusticl: Fix hidden lifetime warnings

Fix the following warning, and others that are similar, as rustc
suggests:

warning: hiding a lifetime that's elided elsewhere is confusing
   --> ../src/gallium/frontends/rusticl/mesa/compiler/nir.rs:282:22
    |
282 |     pub fn variables(&mut self) -> ExecListIter<nir_variable> {
    |                      ^^^^^^^^^     -------------------------- the same lifetime is hidden here
    |                      |
    |                      the lifetime is elided here
    = help: the same lifetime is referred to in inconsistent ways, making the signature confusing
    = note: `#[warn(mismatched_lifetime_syntaxes)]` on by default
help: use `'_` for type paths
