ASoC: check for substream not channels_min in pcm engines This is a follow up on 53dea36c70c1857 which fixes the other affected pcm engines. Description from 53dea36c70c1857: Don't rely on the codec's channels_min information to decide wheter or not allocate a substream's DMA buffer. Rather check if the substream itself was allocated previously. Without this patch I was seeing null-pointer dereferenc in atmel-pcm.
