The recent code refactoring to use the standard DMA helper requires
the max	DMA segment size setup for SG list management.	Without	it,
the kernel may spew warnings when a large buffer is allocated.

This patch sets	up dma_set_max_seg_size() for avoiding spurious
warnings.

Fixes: 2c95b92ecd92 ("ALSA: memalloc: Unify x86 SG-buffer handling (take#3)")
