dma-direct: don't fail on highmem CMA pages in dma_direct_alloc_pages
When dma_direct_alloc_pages encounters a highmem page it just gives up
currently. But what we really should do is to try memory using the
page allocator instead - without this platforms with a global highmem
CMA pool will fail all dma_alloc_pages allocations.
Fixes: efa70f2fdc84 ("dma-mapping: add a new dma_alloc_pages API")
