macvlan: fix panic if lowerdev in a bond

[ Upstream commit d93515611bbc70c2fe4db232e5feb448ed8e4cc9 ]

commit a35e2c1b6d905 (macvlan: use rx_handler_data pointer to store
macvlan_port pointer V2) added a bug in macvlan_port_create()

Steps to reproduce the bug:

# ifenslave bond0 eth0 eth1

# ip link add link eth0 up name eth0#1 type macvlan
->error EBUSY

# ip link add link eth0 up name eth0#1 type macvlan
->panic

Fix: Dont set IFF_MACVLAN_PORT in error case.
