ENGR00300188-2 ASoC: imx-hdmi-dma: Clear offset in the trigger init
The offset reflects the current position of DMA access in the ALSA ring buffer.
So we should clear it before re-start DMA engine becasue the DMA access should
re-start its job from the 0 position. If we don't do this, the driver might get
a wrong idea about current position of DMA access. Thus fix it.
