 Leakfix.

 Will merge to 'next'?

I think it's ready, but I see you peeled of the 2nd and 3rd patch. I
re-rolled a v3 which should address Elijah's outstanding comments there:
with
https://lore.kernel.org/git/cover-v3-0.3-00000000000-20211013T132223Z-avarab@gmail.com/ (local)

I can submit that after this one if you'd like, but having that missing
clear_unpack_trees_porcelain() seems easy enough, and will make that API
and its users leak-free.
