fftools/ffmpeg_filter: do not assume av_buffersrc_get_nb_failed_requests()>0

Browse Source 
Apparently it can happen that avfilter_graph_request_oldest() returns
EAGAIN, yet av_buffersrc_get_nb_failed_requests() returns 0 for every
input.

Works around #10795, though the root issue is most likely in the
scale2ref filter.
