[PATCH v2 22/29] builtin/clone: plug leaking HEAD ref in `wanted_peer_refs()`

[Patrick Steinhardt <ps@pks.im>]

[-- Attachment #1: Type: text/plain, Size: 2131 bytes --]

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.
