State-Changed-Why:
Close this PR. I disabled the KASSERT, because several places put M_PKTHDR
on secondary mbufs, and we're in such a state that it is not possible to
guarantee that this KASSERT is not fired on a regular basis.

So we must assume that the assumption does not hold, even though it would
be theoretically consistent if it did. I added a comment in uipc_mbuf.c.
