Handle ps-poll data frame if_transmit() failure.

If the data frame transmission failures, it may have a node reference
that needs cleaning up.

If the frame is marked as M_ENCAP then it should treat recvif as a node
reference and clear it.

Now - since the mbuf has been freed by calling if_transmit() (even on
failure), the mbuf has to be treated as invalid.  Hence why the ifp is
used.
