Because get_commit_tree() now becomes a compat wrapper (yes I'll fill
in the commit message ;) and should be avoided.

Oooh.. I see now. I actually updated that then dropped, thinking that
a function call cannot be on LHS and that conversion is for
already-long-gone code anyway. But yeah when you stack that conversion
on top of this, it makes sense that we need double conversion to avoid
build error.
Since I will have to update this patch anyway, I'll update the commit
message on the first cocci patch too.
