when the allocator function (snd_malloc_xxx) is called from the
driver.  so, it wouldn't work exactly like snd-hammerfall-mem, which
allocates by itself without call from the sound drivers.
snd-page-alloc module just "caches" the buffer after the module
unload/reload.

but i don't think this would make so big difference, since the sound
drivers are loaded likely in the early stage, anyway.
