This is a redo of earlier cleanup stuff:
* replace DBG() macro with pr_debug()
* get rid of duplicate extern's that are already in fib_lookup.h
* use BUG_ON and WARN_ON
* don't use BUG checks for null pointers where next statement would
get a fault anyway
* remove debug printout when rebalance causes deep tree
* remove trailing blanks
