ASoC: SOF: ipc4-pcm: Invalidate the stream_start_offset in PAUSED state

Browse Source 
BugLink: https://bugs.launchpad.net/bugs/2065400

commit 3ce3bc36d91510389955b47e36ea4c4e94fcbdd3 upstream.

When the final state is SOF_IPC4_PIPE_PAUSED, it is possible that the
stream will be restarted (resume or start) in which case we need to update
the offset from the firmware.
