[PATCH] A couple small changes in *hdump()

[Kris Katterjohn <kjak () ispwest com>]

The attached patch removes a couple unneeded variables and casts from hdump()
and lamont_hdump(). 'j' in hdump() and 'bp' in lamont_hdump() can both be
removed and the other variables used directly. 'length' was cast to u_int when
it's all ready unsigned int.

Thanks,
Kris
