[pbs-devel] [PATCH backup 3/4] report: inline errors in writeln!

[Maximiliano Sandoval <m.sandoval@proxmox.com>]

Fixes the clippy lint:

```
warning: `to_string` applied to a type that implements `Display` in `writeln!` args
   --> src/server/report.rs:141:72
    |
141 |                 let _ = writeln!(out, "error during read-dir - {}", err.to_string());
    |                                                                        ^^^^^^^^^^^^ help: remove this
    |
    = help: for further information visit https://rust-lang.github.io/rust-clippy/master/index.html#to_string_in_format_args
```
