[PATCH v2 04/10] iommu/dma: Use the gfp parameter in __iommu_dma_alloc_noncontiguous()

Change the sg_alloc_table_from_pages() allocation that was hardwired to
GFP_KERNEL to use the gfp parameter like the other allocations in this
function.

Auditing says this is never called from an atomic context, so it is safe
as is, but reads wrong.
