[PATCH] drm/msm/dp: return 0 from audio_prepare when cable is disconnected

[Kumar Anurag <kumar.singh@oss.qualcomm.com>]

PipeWire treats a non-zero return from prepare as fatal, marking the
DP audio device as a dummy sink when the cable is unplugged. The
active_stream_cnt guard already prevents any unclocked hardware access,
so return success instead of -EINVAL when the link is not active.
