[pbs-devel] [PATCH backup 02/13] use inspect_err when possible

[Maximiliano Sandoval]

Fixes the manual_inspect clippy lint:

```
warning: using `map_err` over `inspect_err`
   --> src/bin/proxmox_backup_debug/diff.rs:125:18
    |
125 |                 .map_err(|err| {
    |                  ^^^^^^^
    |
    = help: for further information visit https://rust-lang.github.io/rust-clippy/master/index.html#manual_inspect
    = note: `#[warn(clippy::manual_inspect)]` on by default
help: try
    |
125 ~                 .inspect_err(|err| {
126 ~                     log::error!("{}", format_key_source(&key.source, "encryption"));
    |
```
