Fix no_global_oom_handling build

`provide_sorted_batch` in core is incorrectly marked with `#[cfg(not(no_global_oom_handling))]` which prevents core from building with the cfg enabled.

Nothing in `core` allocates memory (including this function). The `cfg` gate is incorrect.

The cfg was added by rust-lang#107191
