From: Tariq Toukan <tariqt@nvidia.com>

Move the logic that updates the page pool upon changes in numa node.
Before this patch, logic was placed in the RX polling function, being
called also when no RX traffic, wasting cpu cycles.  Here we move it to
the RX post_wqes function, to be called only when new RX descriptors are
going to be allocated.
