From: Alvin Šipraga <alsi@xxxxxxxxxxxxxxx>
commit 43a4b4dbd48c9006ef64df3a12acf33bdfe11c61 upstream.
Flip the sign of a return value check, thereby suppressing the following
spurious error:
port 2 failed to notify DSA_NOTIFIER_BRIDGE_LEAVE: -EOPNOTSUPP
... which is emitted when removing an unoffloaded DSA switch port from a
bridge.
Fixes: d371b7c92d19 ("net: dsa: Unset vlan_filtering when ports leave the bridge")
