[RFC PATCH v3 4/9] fs/btrfs/extent_io: update usage of zone modifiers

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