[PATCH] improve MOD_DPF macro and other misc. cleanup

[Garrett Cooper]

Hi Doug,
   I tried using the MODULE_DEBUG #define and I ran into some compile
issues. This patch gets things to work and adds an official option /
entry to NOTES for help with other folks debugging kern_module.c
logic. I also added some additional data to assist with determining
causes of failure, as well as remove an impossible == NULL case when
using malloc(.., M_WAITOK).
Thanks!
