Subject: [PATCH 2/3] policy-node: wait for nodes when we become unlinked

If we were linked before but our node is removed, wait until a new node
becomes available instead of failing.

This fixes an issue where there is only 1 sink available and the card
profile is toggeled between pro and stereo. After the profile is
toggled, the sink is removed and the node would be killed with an error
because there is no fallback sink. The fix is similar to the
pipewire-media-session logic.
