Subject: merge-ort: clean up after failed merge

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.

Subject: merge-ort: do leave trace2 region even if checkout fails

In 557ac0350d9 (merge-ort: begin performance work; instrument with
trace2_region_* calls, 2021-01-23), we added Trace2 instrumentation, but
in the error path that returns early, we forgot to tell Trace2 that
we're leaving the region. Let's fix that.
