I doubt it. skb_morph is only used on IP fragments so I don't see how you could attribute an error from a Unix domain socket to this patch.
In any case, Unix socket packets should not have a dst at all so the very fact that you're in that path means that you have some sort of memory corruption.
Is this the very first OOPS/warning that you see? If not you should ignore all but the very first one as that may have left your system in an inconsistent state which may render all subsequent OOPSes and warnings useless.
