ipv6: reallocate addrconf router for ipv6 address when lo device up commit 25fb6ca4ed9cad72f14f61629b68dc03c0d9713f "net IPv6 : Fix broken IPv6 routing table after loopback down-up" allocates addrconf router for ipv6 address when lo device up. but commit a881ae1f625c599b460cc8f8a7fcb1c438f699ad "ipv6:don't call addrconf_dst_alloc again when enable lo" breaks this behavior. Since the addrconf router is moved to the garbage list when lo device down, we should release this router and rellocate a new one for ipv6 address when lo device up.
