Vivien Didelot af72f60663 net: dsa: fix preparation of a port STP update ...

[ Upstream commit 57a47532c4 ]

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.
