BUILD: listener: silence a build warning about unused value without threads

A variable introduced in commit 1a43b9f32c ("MINOR: proto: extend
connection thread rebind API") is not used without threads and causes a
build warning. Let's just mark it maybe_unused.

Since the commit above is tagged for backporting, this one will need to
be backported along with it.
