ASoC: fsi: don't reschedule DMA from an atomic context
commit 57451e437796548d658d03c2c4aab659eafcd799 upstream.
shdma doesn't support transfer re-scheduling or triggering from callbacks
or from atomic context. The fsi driver issues DMA transfers from a tasklet
context, which is a bug. To fix it convert tasklet to a work.
