macvlan: resolve ENOENT errors on creation
After the commit below attempting to create macvlan devices was
resulting in ENOENT errors,
# ip link add link p3p2 type macvlan
RTNETLINK answers: Invalid argument
This happens because netdev_upper_dev_link() is called before
register_netdevice() in the macvlan code. Through a call chain
this results in a call to __netdev_adjacent_dev_insert() and
finally a sysfs_create_link(). This requires the kobject of
the macvlan to be registered which is done in register_netdevice().
If there is no kobject which is the case here the ENOENT error
is seen on the command line.
To resolve this move the netdev_upper_dev_link() call below
the register_netdevice() call. This aligns with vlan driver
flow.
Regression introduced here,
