Marton Balint ff0f25a154 avfilter/f_loop: fix length of aloop leftover buffer 
If the audio loop stops inside an audio frame, the leftover buffer contains the
end of the frame, which is not looped. The length supposed to be the part which
was not written to the loop buffer, so we need to drain exactly that number of
bytes from the leftover buffer.
