Subject: [PATCH] ALSA: au88x0: Fix calculation in vortex_wtdma_bufshift()

commit 62db7152c924e4c060e42b34a69cd39658e8a0dc upstream.

vortex_wtdma_bufshift() function does calculate the page index
wrongly, first masking then shift, which always results in zero.
The proper computation is to first shift, then mask.
