ALSA: compress: fix an integer overflow check
I previously added an integer overflow check here but looking at it now,
it's still buggy.
The bug happens in snd_compr_allocate_buffer(). We multiply
".fragments" and ".fragment_size" and that doesn't overflow but then we
save it in an unsigned int so it truncates the high bits away and we
allocate a smaller than expected size.
Fixes: b35cc8225845 ('ALSA: compress_core: integer overflow in snd_compr_allocate_buffer()')
