[Virtio-fs] [virtiofsd] MR merged: Fix nightly clippy derive_partial_eq_without_eq warning

[virtiofs-bot at sinrega.org]

The nightly version of clippy (v1.63.0) warns about implementing
`PartialEq` without implementing `Eq` when all the member of the
`struct` or `enum` implement both:

```
#[derive(Debug, Copy, Clone, PartialEq)]
                             ^^^^^^^^^ help: consider deriving `Eq` as well: `PartialEq, Eq`
```
