dpaa2-switch: fix VLAN upper check not rejecting bridge join

Browse source

[ Upstream commit ed2294f94e ]

The blamed commit refactored the prechangeupper event handling but
failed to actually return an error in case
dpaa2_switch_prevent_bridging_with_8021q_upper() detected a 802.1q upper
on a port which tries to join a bridge. Fix this by returning err
instead of 0.
