net: dsa: avoid calling ds->ops->port_hsr_leave() when unoffloaded
This mirrors what we do in dsa_port_lag_leave() and
dsa_port_bridge_leave(): when ds->ops->port_hsr_join() returns
-EOPNOTSUPP, we fall back to a software implementation where dp->hsr_dev
is NULL, and the unoffloaded port is no longer bothered with calls from
the HSR layer.
This helps, for example, with interlink ports which current DSA drivers
don't know how to offload. We have to check only in port_hsr_join() for
the port type, then in port_hsr_leave() we are sure we're dealing only
with known port types.
