qtdemux: Stop pushing data as soon as possible in push-modeqtpushfix

When working in push-mode, we attempt to push out everything currently
buffered in the adapter.

This has two pitfalls:
* We could stop earlier (the moment we get a non-ok or non-not-linked)
* We return the last combined flow return, which might be completely
  different from the previous combined flow return
