ALSA: pcm: Use dma_mmap_coherent() on x86, too
We avoided the explicit use of dma_mmap_coherent() on x86 because of a spurious warning in x86 APT code in the past. However, this blindly assumes that the pages allocated via dma_alloc_coherent() on x86 are the ones convertible via virt_to_page() (that is used in the default mmap handler), and it's no longer true; with the indirect DMA ops, this can be handled differently. The only certain way for doing mmap such pages is the dma_mmap_coherent(), and the warning seems already gone in the recent code, so let's use it consistently.
