Subject: [PATCH 07/13] rust: kernel: unify spelling of refcount in docs

Replace instances of 'ref-count[ed]' with 'refcount[ed]' to increase
consistency within the Rust documentation. The latter form is used more
widely in the rest of the kernel:

```console
$ rg '(\*|//).*?\srefcount(|ed)[\s,.]' | wc -l
1605
$ rg '(\*|//).*?\sref-count(|ed)[\s,.]' | wc -l
43
```

(numbers are for Commit 052d534373b7)
