hevcdec: properly export some side data with frame threading

I noticed this with mastering display data. If frame threading is
enabled, this side data is exported only for some frames. It turns out
it's not properly propagated to the worker threads.

I didn't touch A53 captions, because that involves memory allocation and
freeing the data as side data is exported.

Micro bump so that API users can detect the bug fix.
