Christian Schwarz 939593d0d3 refactor check_checkpoint_distance to prepare for async Timeline::layers (#4476) ...

This is preliminary work for/from #4220 (async
`Layer::get_value_reconstruct_data`).

There, we want to switch `Timeline::layers` to be a
`tokio::sync::RwLock`.

That will require the `TimelineWriter` to become async.

That will require `freeze_inmem_layer` to become async.

So, inside check_checkpoint_distance, we will have
`freeze_inmem_layer().await`.

But current rustc isn't smart enough to understand that we
`drop(layers)` earlier, and hence, will complain about the `!Send`
`layers` being held across the `freeze_inmem_layer().await`-point.

This patch puts the guard into a scope, so rustc will shut up in the
next patch where we make the transition for `TimelineWriter`.
