Alexander Mikhalitsyn 9bedee7cdf af_unix: rework unix_maybe_add_creds() to allow sleep ...

As a preparation for the next patches we need to allow sleeping
in unix_maybe_add_creds() and also return err. Currently, we can't do
that as unix_maybe_add_creds() is being called under unix_state_lock().
There is no need for this, really. So let's move call sites of
this helper a bit and do necessary function signature changes.
