PR #22953: Fix const qualifier on status prevents automatic move semantics

Imported from GitHub PR #22953

reason for change - const qualifier on `status` prevents automatic move semantics in return.

When return status; is executed, the compiler cannot invoke the move constructor of `absl::Status` because status is const.
