[RFC PATCH v3 3/9] drivers/xen/swiotlb-xen: update usage of zone modifiers

From: Huaisheng Ye Use __GFP_ZONE_MASK to replace (__GFP_DMA | __GFP_HIGHMEM). In function xen_swiotlb_alloc_coherent, it is obvious that __GFP_DMA32 is not the expecting zone type. ___GFP_DMA, ___GFP_HIGHMEM and ___GFP_DMA32 have been deleted from GFP bitmasks, the bottom
