avio: Do not consider the end-of-buffer position valid Trigger a refill if the seek action moves the pointer at the end of the buffer. Before this patch the read action following the seek would trigger the refill, while write action would write outside the buffer. In the Libav codebase few muxers seek forward outside of what already has been written so it is quite unlikely to experience the problem with the default buffer size.
