Ruiling Song a768c0a3e1 lavf/qsv: clone the frame which may be managed by framework
For filters based on framesync, the input frame was managed
by framesync, so we should not directly keep and destroy it,
instead we make a clone of it here, or else double-free will occur.
But for other filters not based on framesync, we still need to
free the input frame inside filter_frame.
