update location log for missing content during direct mode conversion
If a direct mode file is deleted or modified, and there are no other
files containing the content, the content was lost. That's a normal
thing that can happen in direct mode, but not in v7, so the upgrade
code has to notice it in order for the location log to be accurate.

Upgrading a direct mode repo to v7 while it has a deleted file in it
behaves strangely. This is after my recent change to not make it commit.
A `git checkout` of the file checks out the pointer file, as the content
of the file is not present. This is as expected.
But `git whereis` thinks the content is present, which it's not any longer.
Seems that the upgrade process needs to notice when a deleted file was the
only copy of the content, and set its content as not present.

And `git fsck` doesn't find a problem, despite the content not being
present. And does not fix the location log.
This part may not be specific to this case, seems it must be some bug in
fsck?
