It's what hostmux does. It doesn't matter much, you could also fail
with an assertion, as this case should never occur (.. in the root
directory is handled by netfs_S_dir_lookup).
There are several such places where an error is returned instead failing
with an assertion. Mmmh. It doesn't matter too much either way.
