ASoC: SOF: Intel: hda-stream: Fix incorrect variable used in error message

[ Upstream commit 35fc531a ]

The dev_err message is reporting an error about capture streams however
it is using the incorrect variable num_playback instead of num_capture.
Fix this by using the correct variable num_capture.
