WA: Queue extra buffers on output port during reconfig if input EOS-ed

Some codecs may return input buffers before having them processed.
This causes a halt if we already signaled an EOS on the input
port.  For now keep submitting output meta buffers one at a time if
the input EOS-ed, but the output not yet.

Normally, we submit an output buffer for each input buffer that is
with the component (waiting to be processed).
