ASoC: fsl_asrc_m2m: only handle pairs for m2m in the suspend

Browse Source 
ASRC memory to memory cases and memory to peripheral cases are
sharing the same pair pools, the pairs got for m2m suspend
function may be used for memory to peripheral, which is handled
memory to peripheral driver and can't be handled in
memory to memory suspend function.

Use the "pair->dma_buffer" as a flag for memory to memory case,
when it is allocated, handle the suspend operation for the related
pairs.
