[pbs-devel] [PATCH backup 04/13] push: use unwrap_or to prevent lazy evaluation

[Maximiliano Sandoval]

Fixes the unnecessary_lazy_evaluations clippy lint:

```
warning: unnecessary closure used to substitute value for `Option::None`
   --> src/server/push.rs:445:25
    |
445 |           let max_depth = params
    |  _________________________^
446 | |             .max_depth
447 | |             .unwrap_or_else(|| pbs_api_types::MAX_NAMESPACE_DEPTH);
    | |__________________________________________________________________^
    |
    = help: for further information visit https://rust-lang.github.io/rust-clippy/master/index.html#unnecessary_lazy_evaluations
    = note: `#[warn(clippy::unnecessary_lazy_evaluations)]` on by default
help: use `unwrap_or` instead
    |
447 |             .unwrap_or(pbs_api_types::MAX_NAMESPACE_DEPTH);
    |              ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
```
