[PATCH] threadpool: use all available threads on each NUMA node with --pools=NULL option too


from x265.readthedocs, --pools = NULL, "", "*" are doing same functionality.
--pools="" & --pools="*" are using all threads but when we pass --pools=NULL, disabled
all threads pools but supposed to enable.
