Currently, the per-numa buffer allocation doesn't support skipping the
allocation altogether for a particular NUMA domain - if it's set to
zero, it instead uses the default allocation.
Therefore, this changes the behavior so that the default is only used
if no per-numa allocation is specified, and an allocation of zero
is honored by not allocating a buffer at all.
