selftests: forwarding: hw_stats_l3: Set addrgenmode in a separate step
Setting the IPv6 address generation mode of a net device during its creation never worked, but after commit b0ad3c179059 ("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.
