[IPV6]: Fix refcounting for anycast dst entries. The problem occures when we stop IPv6 device without dropping all addresses on it. For such a device addrconf_ifdown marks all entries as obsolete and ip6_del_rt called from __ipv6_dev_ac_dec return ENOENT. The referrence is not dropped. The fix is simple. DST entry should not keep referrence when stored in the FIB6 tree. Signed-off-by: Denis V. Lunev <den@openvz.org>
