Multiqueue needs some unrelated fixes still

    queue/queue2: Protect against spurious condition variable wakeups

    Make sure that we only wake up when we have to flush, or when this
    specific query was handled.

commit 33c239828bd0563114fddb4fece75f95a986d41e

    queue/queue2: Ensure that the streaming thread is unlocked after
deactivating the srcpad

    It might happen that the srcpad task function is never called at all, in
    which case unlocking everything from there will never happen.

    Make sure to unlock everything another time after the task function is
    definitely stopped.
