Fix condition for ffmpeg seek workaround

This condition was in contradiction with comment for function
`ffmpeg_generic_seek_workaround()`.

I have noticed, that formats that seeked well used this workaround.
Problem was that I misunderstood code from `av_seek_frame()` - formats
with `read_seek()` function stil don't use generic seeking method.
This is defined in `seek_frame_internal()`
