Focus on code where we are doing multiplications within malloc(9). None of these ire likely to overflow, however the change is still useful as some static checkers can benefit from the allocation attributes we use for mallocarray. This initial sweep only covers malloc(9) calls with M_NOWAIT. No good reason but I started doing the changes before r327796 and at that time it was convenient to make sure the sorrounding code could handle NULL values.
