This patch improves the performance of Vaapi Encode by enabling

only if the frame hasn't been flushed yet.
Sorry I didn't see this before it went in, but it breaks cqp encoding
on tonga. cbr seems OK (but is slower than cqp).
Not every run will be corrupt. On runs that are the corruption seems
to be on/around IDR frames, though that's just a guess judging by
frequency.
Oops - It is OK, the problem seems to be that I was testing UHD and that
needs a patch - which turns out to be useless in combination with this,
haven't worked out why yet.
