MLK-13992: ASoC: fsl_rpmsg_i2s: add flush workqueue
some cmd is sent by workqueue, others are sent by call send message
function directly, for workqueue may have delay, so there is occasion
that cmd is not sent in order.
Add flush_workqueue before the CLOSE and SUSPEND to make sure previous
cmd is finished in that time.
