dsa_slave_prechangeupper_sanity_check() is supposed to enforce some
adjacency restrictions, and calls ds->ops->port_prechangeupper if the
driver implements it.
We convert the error code from the port_prechangeupper() call to a
notifier code, and 0 is converted to NOTIFY_OK, but the caller of
dsa_slave_prechangeupper_sanity_check() stops at any notifier code
different from NOTIFY_DONE.
Avoid this by converting back the notifier code to an error code, so
that both NOTIFY_OK and NOTIFY_DONE will be seen as 0. This allows more
parallel sanity check functions to be added.
