s390/dma: provide proper ARCH_ZONE_DMA_BITS value
On s390 ZONE_DMA is up to 2G, i.e. ARCH_ZONE_DMA_BITS should be 31 bits.
The current value is 24 and makes __dma_direct_alloc_pages() take a
wrong turn first (but __dma_direct_alloc_pages() recovers then).
Let's correct ARCH_ZONE_DMA_BITS value and avoid wrong turns.
