avformat/avidec: Don't reimplement ff_free_stream()

Using ff_free_stream() makes the code more readable, more future-proof
(the old code freed AVCodecContexts and AVCodecParameters and its
substructures manually, so that there is a chance that there would be a
memleak for some time if new substructures were added) and reduces
code size.
