ALSA: seq: fix kvmalloc_array() arguments order

Browse Source 
When compiling with gcc version 14.0.0 20231220 (experimental)
and W=1, I've noticed the following warning:

sound/core/seq/seq_memory.c: In function 'snd_seq_pool_init':
sound/core/seq/seq_memory.c:445:41: warning: 'kvmalloc_array' sizes specified with
'sizeof' in the earlier argument and not in the later argument [-Wcalloc-transposed-args]
  445 |         cellptr = kvmalloc_array(sizeof(struct snd_seq_event_cell), pool->size,
      |                                         ^~~~~~

Since 'n' and 'size' arguments of 'kvmalloc_array()' are multiplied
to calculate the final size, their actual order doesn't affect the
result and so this is not a bug. But it's still worth to fix it.
