5e715b583d avcodec/dolby_e: fix potentially undefined pointer arithmetic 
Avoid undefined behavior in skip_input() by checking that enough data is
available before incrementing input pointer.

Check return values of parse_key() and skip_input() and exit early with
error if there is not enough data.
