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.
