pfg d269f13cdd Use mallocarray(9) in dirhash.
Basic use of mallocarray to prevent overflows. Here allocation is done
with M_NOWAIT so the code is prepared for the possibility of returning
NULL values. Since mallocarray expects unsigned parameters, unsign some
related variables to minimize sign conversions.
