Vivien Didelot 57a47532c4 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: 3563606258 ("switchdev: convert STP update to switchdev attr set")
