Subject: [PATCH] Remove unused-variable in
 dumbo/backup/dumbo/service/tests/ChainReplicatorTests.cpp +3 (#4024)

Summary:
Pull Request resolved: https://github.com/facebookresearch/faiss/pull/4024

LLVM-15 has a warning `-Wunused-variable` which we treat as an error because it's so often diagnostic of a code issue. Unused variables can compromise readability or, worse, performance.

This diff either (a) removes an unused variable and, possibly, it's associated code or (b) qualifies the variable with `[[maybe_unused]]`.
