This series reduces duplication between __xa_cmpxchg and __xa_insert by
extracting a new function that does not coerce zero entries to null on
the return path.
The new function may be used by the upcoming Rust xarray abstraction in
its reservation API where it is useful to tell the difference between
zero entries and null slots.
