Linjie Fu 87368884a5 lavc/qsvdec: flush buffered data before reinit
Flush the buffered data in libmfx before video param reinit
in case the frames drop.

Cache the first frame causing the reinit and decode zero-size
pkt to flush the buffered pkt before reinit. After all the
buffered pkts being flushed, resume to reinit and decode.

Fix the issue in ticket #7399.

[V2]: Move the definition of zero_pkt to where it is exactly
used.
