bridge: T4565: bugfix error message when member interface contains an address

We should not print the entire dictionary - we only need the bridge interface
name:

Bug:
Cannot assign address to interface "eth1" as it is a member of bridge
"{'br0': {'allowed_vlan': ['5-50', '101'], 'native_vlan': '101'}}"!

Fixed:
Cannot assign address to interface "eth1" as it is a member of bridge
"br0"!
