If the source is using a custom IO, setting this flag causes heavy leaks
since the segments will not have their avio context closed.

Using AVOnce as a stack variable makes no sense as the state is lost

fc3a03fcf9 avfilter: take_samples: do not directly return frame when samples are skipped 
Modifying data pointer when skipping samples may make it unaligned.
Workaround for Ticket6349.

This should fix the crash of ticket's testcase and a crash/regression
with avxsynth (reported by Michael Niedermayer).

Also change frame->nb_samples < max to frame->nb_samples <= max.
This improves performance. Benchmark:
./ffmpeg -filter_complex "aevalsrc=0:n=1166,firequalizer=fixed=on" -f null null
