[PATCH 5.4 119/168] ASoC: SOF: Fix snd_sof_ipc_stream_posn()

From: Dan Carpenter <dan.carpenter@oracle.com>

commit 613cea5935e83cb5a7d182ee3f98d54620e102e2 upstream.

We're passing "&posn" instead of "posn" so it ends up corrupting
memory instead of doing something useful.

Fixes: 53e0c72d98ba ("ASoC: SOF: Add support for IPC IO between DSP and Host")
