Fix minor error it SDCH filter code (hidden by filter control code)

The controlling code in filter.cc doesn't significantly distinguish
FILTER_OK and FILTER_NEEDS_MORE_DATA, but we *should* transition
to a semantic where FILTER_OK becomes instead "FILTER_NEEDS_OUTPUT_SPACE"
and then we'd need to do this uniformly for all filter code.
We *could* then improve the driving filter code (for example, not have
to sniff output buffer usage to deduce that the filter wanted to be 
called again to emit more data).
