From: Alvin Šipraga <alsi@bang-olufsen.dk>

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")
