afifo: fix request_samples on the last frame in certain cases
The current code can fail to return the last frame if it contains exactly the requested number of samples. Fixes the join filter test, which previously did not include the last 408 samples in most cases. CC:libav-stable@libav.org Signed-off-by: Diego Biurrun <diego@biurrun.de>
