ipv6: do not erase dst address with flow label destination

This patch is following b579035 "ipv6: remove old conditions on flow label sharing" Since there is no reason to restrict a label to a destination, we should not erase the destination value of a socket with the value contained in the flow label storage. This patch allows to really have the same flow label to more than one destination.
