Logically incorrect `await` statement could cause deadlock at some point

Apache Iceberg Rust version

None

Describe the bug

We're awaiting on a spawned task that should proceed concurrently rather than being awaited upon. This could cause deadlock at some point (I experienced this whilst working on #1011 and thought it best to backport the fix).

To Reproduce

No response

Expected behavior

No response

Willingness to contribute

I can contribute a fix for this bug independently

Turns out this was not the cause of deadlock. Closing
