Here is more info and a possible (shocking) explanation. This
aggregates my prior messages and it provides an almost complete set of
steps to reproduce this problem.

In fuzz-tests/004-simple-dump-tree:
Since there is one wrong item(DATA_RELOC_TREE CHUNK_ITEM 0) in root
tree.
It fails as follow:

This new test checks inspect-internal rootid
- handle path to subvolume/directory/file as an argument
- get different id for each subvolume
- get the expected id for each file/directory (i.e. the same as
containing subvolume)
