[22/29] builtin/clone: plug leaking HEAD ref in `wanted_peer_refs()`

Commit Message

Patrick Steinhardt June 3, 2024, 9:48 a.m. UTC

In `wanted_peer_refs()` we first create a copy of the "HEAD" ref. This
copy may not actually be passed back to the caller, but is not getting
freed in this case. Fix this.
