notifier: change notifier_from_errno(0) to return NOTIFY_OK

This changes notifier_from_errno(0) to be NOTIFY_OK instead of
NOTIFY_STOP_MASK | NOTIFY_OK.

Currently, the notifiers which return encapsulated errno value have to
do something like this:

err = do_something(); // returns -errno
if (err)
return notifier_from_errno(err);
else
return NOTIFY_OK;

This change makes the above code simple:

err = do_something(); // returns -errno

return return notifier_from_errno(err);
