Nicolas Saenz Julienne 1ca28e0d9e dma-pool: Only allocate from CMA when in same memory zone ...

[ Upstream commit d7e673ec2c ]

There is no guarantee to CMA's placement, so allocating a zone specific
atomic pool from CMA might return memory from a completely different
memory zone. To get around this double check CMA's placement before
allocating from it.
