Causes a divide-by-zero in the rare case where:
- the file has an audio stream,
- the first audio frame isn't within the first BRP_BASF_LOOKAHEAD frames,
- an audio frame is encountered later, and
- its chunk header (except num_blocks) contains all zeros
(matching the uninitialised structure in the context)
The decoder will discard any garbage data, so the check isn't really needed.
Fixes: division by 0
