interfaces: T4331: Fix assign link-local static IPv6 addr to vrf

If we have link-local static address and vrf, for example:
set interfaces ethernet eth2 address 'fe80::5200:ff:fe55:222/64'
set interfaces ethernet eth2 vrf 'foo'

This IPv6 address was assigned before vrf, as result after
attaching the intreface to vrf we lose this static linklocal
address

DEBUG/IFCONFIG cmd 'ip addr add fe80::5200:ff:fe55:222/64 dev eth2'
DEBUG/IFCONFIG cmd 'ip link set dev eth2 master foo'
DEBUG/IFCONFIG cmd 'ip addr add fe80::5208:ff:fe13:2/64 dev eth2'

This commit fixes this, the address is assigned after vrf assign
