ALSA: correct kcalloc usage

kcalloc is supposed to be called with the count as its first argument and the
element size as the second.

Both arguments are size_t so does not affect correctness.  This callsite is
during module_init and therefore not performance critical.  Another patch will
optimize the case when the count is variable but the size is fixed.
