asfdemux: fix seeking back after EOS has been reached in push mode

Fix seeking when demuxer is in INDEX state. This happens when we
reached the end of the stream. It should still be possible to do
a flushing seek and seek back to any other position though. Instead
the demuxer would just go straight to EOS again instead of going
back to processing packets again from the new position.
