Kees Cook 12626530de ALSA: lola: Bounds check loop iterator against streams array size
GCC 12 sees that it's technically possible for num_streams to be larger
than ARRAY_SIZE(pcm->streams). Bounds-check the iterator.

../sound/pci/lola/lola_pcm.c: In function 'lola_pcm_update':
../sound/pci/lola/lola_pcm.c:567:64: warning: array subscript [0, 31] is outside array bounds of 'struct lola_stream[16]' [-Warray-bounds]
  567 |                         struct lola_stream *str = &pcm->streams[i];
      |                                                    ~~~~~~~~~~~~^~~
