In the source address selection, the address must be sorted
from global to node-local.
But, ifp->scope is different from the scope for source address
selection.
2001::1 fe80::1 ::1
ifp->scope 0 0x02 0x01
ipv6_addr_src_scope(&ifp->addr) 0x0e 0x02 0x01
So, we need to use ipv6_addr_src_scope(&ifp->addr) for sorting.
And, for backward compatibility, addresses should be sorted from
new one to old one.
