In 9fefce68dc8 (merge-ort: basic outline for merge_switch_to_result(),
2020-12-13), we added functionality to lay down the result of a merge on
disk. But we forgot to release the data structures in case
`unpack_trees()` failed to run properly.

This was pointed out by the `linux-leaks` job in our CI runs.
