ALSA: au88x0: fix incorrect left shift
vortex_wt_setdsout performs bit-negation on the bit position (wt&0x1f) rather than on the resulting bitmask. This code is never actually invoked (vortex_wt_setdsout is always called with en=1), so this does not currently cause any problem, and this patch is simply cleanup.
