Setting the IPv6 address generation mode of a net device during its
creation never worked, but after commit b0ad3c1790 ("rtnetlink: call
validate_linkmsg in rtnl_create_link") it explicitly fails [1]. The
failure is caused by the fact that validate_linkmsg() is called before
the net device is registered, when it still does not have an 'inet6_dev'.

Likewise, raising the net device before setting the address generation
mode is meaningless, because by the time the mode is set, the address
has already been generated.

Therefore, fix the test to first create the net device, then set its
IPv6 address generation mode and finally bring it up.
