Revert a portion of kern_malloc.c:1.99, which (in addition to adding

malloc profiling) also modified the set of pre-defined buckets for the
memory allocator.  For reasons unknown to me, this resulted in extensive
memory corruption in the kernel, in particular on SMP boxes, so I'm
committing this work-around until Jeff gets a chance to debug it
properly.  David Wolfskill pointed me at this commit as the one that
might be a problem; I've been running this code on two dual-processor
burn-in boxes for about 12 hours now, and the rate of panics due to
memory corruption has dropped to zero (from one every five minutes).

Hopefully not treading on the toes of:	jeff
