[PATCH hurd-dde 6/7] libmachdev: fix size of `net_rcv_msg' message

[Justus Winter]

Account for the `struct packet_header' that is prepended to the
network packet in the calculation of the `net_rcv_msg' message.  This
complements e363aa56.

* libmachdev/net.c (netif_rx_handle): Fix size of message.
