dma-direct: don't retry allocation for no-op GFP_DMA
When an allocation with lower dma_coherent mask fails, dma_direct_alloc()
retries the allocation with GFP_DMA. But, this is useless for
architectures that hav no ZONE_DMA.
Fix it by adding the check of CONFIG_ZONE_DMA before retrying the
allocation.
