ALSA: pcm: Protect call to dma_mmap_coherent() by check for HAS_DMA
If NO_DMA=y: sound/core/pcm_native.o: In function `snd_pcm_lib_default_mmap': pcm_native.c:(.text+0x144c): undefined reference to `bad_dma_ops' pcm_native.c:(.text+0x1474): undefined reference to `dma_common_mmap' Add a check for HAS_DMA to fix this.
