net: dsa: fix preparation of a port STP update
Because of the default 0 value of ret in dsa_slave_port_attr_set, a
driver may return -EOPNOTSUPP from the commit phase of a STP state,
which triggers a WARN() from switchdev.
This happened on a 6185 switch which does not support hardware bridging.
Fixes: 3563606258cf ("switchdev: convert STP update to switchdev attr set")
