bevy_ecs: remove use of needless_return (#19859)

# Objective

- bevy_ecs has a expected lint that is both needed and unneeded

## Solution

- Change the logic so that it's always not needed

## Testing

`cargo clippy -p bevy_ecs --no-default-features --no-deps -- -D
warnings`

crates/bevy_ecs/src/storage/resource.rs
