notes: fix memory leak when pruning notes
In `prune_notes()` we first store the notes that are to be deleted in a local list, and then iterate through that list to delete those notes one by one. We never free the list though and thus leak its memory. Fix this. Signed-off-by: Patrick Steinhardt <ps@pks.im> Signed-off-by: Junio C Hamano <gitster@pobox.com>
