In the commit [15c75b09f8d1: ALSA: ctxfi: Fallback DMA mask to 32bit], I forgot to put "!" at dam_set_mask() call check in cthw20k1.c (while cthw20k2.c is OK). This patch fixes that obvious bug.

(As a side note: although the original commit was completely wrong, it's still working for most of machines, as it sets to 32bit DMA mask in the end. So the bug severity is low.)
