The protocol requires that the fetcher signals to the remote that it
is done with the fetching process, so that the remote can exit out of
its upload-pack process.
The first change is that the `done` signal can happen before the
validation, since nothing else needs to be fetched.
The second change is that the fetcher does not care if the remote
responds to this signal since it has the data required for validation
and applying the changes to its refdb. Thus, if an error is
encountered then it is logged, but the rest of the process proceeds as
normal.
