ALSA: wss: Fix invalid snd_free_pages() at error path
commit 7b69154171b407844c273ab4c10b5f0ddcd6aa29 upstream.
Some spurious calls of snd_free_pages() have been overlooked and
remain in the error paths of wss driver code. Since runtime->dma_area
is managed by the PCM core helper, we shouldn't release manually.
Drop the superfluous calls.
