x86/pci/dma: Fix gfp flags for coherent DMA memory allocation
Commit 6894258eda2f reversed the order of gfp_flags adjustment in
dma_alloc_attrs() for x86 [arch/x86/kernel/pci-dma.c] As a result,
relevant flags set by dma_alloc_coherent_gfp_flags() are just
discarded and cause coherent DMA memory allocation failure on some
devices.
Fixes: 6894258eda2f ("dma-mapping: consolidate dma_{alloc,free}_{attrs,coherent}")
