buffers: support disabling allocation per numa domain
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.
Type: improvement

^^^^^^^^^^^^^^^
The number of buffers allocated for this specific NUMA domain.
-Default is 0, which falls back to the value configured in **buffers-per-numa**.
+If this is set to zero, no buffers are allocated for this domain.
+
+By default, the value configured in **buffers-per-numa** is used.
