[Security]FPE in alsa-utils axfer `wave_parser_pre_process

alsa-project/alsa-utils issue #332 was opened from eglonnnn:

### Description

A floating point exception vulnerability in alsa-utils v1.2.15.2. When `axfer`'s WAVE container parser processes a crafted WAVE file missing the `fmt` chunk, `samples_per_frame` and `frames_per_second` remain zero, causing a division-by-zero in `wave_parser_pre_process()`.

### Impact

- Denial-of-service via process crash
- Any user processing untrusted WAVE files with axfer is affected

### Reproduction

All materials are available in my research repository:
