[PATCH] source-output: Get the correct source for "direct_on_input" streams

[tanu.kaskinen@xxxxxxxxxxxxxxx (Tanu Kaskinen)]

If a capture stream captures from a single sink input (so the capture
stream is a so called "direct on input" stream), then it needs to
connect to the monitor source of the sink to which the sink input is
connected. Previously the correct source was not figured out
automatically, causing the capture stream creation to fail.
