fix memset overflow in oldmalloc race fix overhaul
commit 3e16313f8fe2ed143ae0267fd79d63014c24779f introduced this bug by making the copy case reachable with n (new size) smaller than n0 (original size). this was left as the only way of shrinking an allocation because it reduces fragmentation if a free chunk of the appropriate size is available. when that's not the case, another approach may be better, but any such improvement would be independent of fixing this bug.
