When prepending space onto outgoing UDP datagram payloads to hold the
UDP/IP header, make sure that space is also allocated for the link
layer header.  If an mbuf must be allocated to hold the UDP/IP header
(very likely), then this will avoid an additional mbuf allocation at
the link layer.  This trick is also used by TCP and other protocols to
avoid extra calls to the mbuf allocator in the ethernet (and related)
output routines.
