ASoC: rsnd: fixup DMAEngine API
commit d5bb69dc54ec1 ("ASoC: sh: rcar: dma: : use proper DMAENGINE
API for termination") updated DMAEngine API _all() to _sync(),
but it should be _async().
_all() and _async() are almost same, the difference is only return
error code. _sync() will call dmaengine_synchronize() and will be
kernel panic.
This patch is needed for v5.15 or later.
