rust: devres: fix private intra-doc link

commit ff4d2ef3874773c9c6173b0f099372bf62252aaf upstream.

The future move of pin-init to `syn` uncovers the following private
intra-doc link:

    error: public documentation for `Devres` links to private item `Self::inner`
       --> rust/kernel/devres.rs:106:7
        |
    106 | /// [`Self::inner`] is guaranteed to be initialized and is always accessed read-only.
        |       ^^^^^^^^^^^ this item is private
        |
        = note: this link will resolve properly if you pass `--document-private-items`
        = note: `-D rustdoc::private-intra-doc-links` implied by `-D warnings`
        = help: to override `-D warnings` add `#[allow(rustdoc::private_intra_doc_links)]`

Currently, when rendered, the link points to "nowhere" (an inexistent
anchor for a "method").

Thus fix it.
