Nicholas J. Kain 9f87bd8b30 udp_checksum(): Clamp the value of the UDP packet header length. 
Without this change, it is possible for malicious UDP packets to
make the function read past the end of a buffer.

If this was ever a possibility in ndhc, the previous commit fixed
that issue, but there is no reason for udp_checksum() to have
such a subtle precondition to proper use.  This change also makes
it easier to audit correctness.
