ALSA: ctxfi: Fallback DMA mask to 32bit
commit 15c75b09f8d190f89ab4db463b87d411ca349dfe upstream.
Currently ctxfi driver tries to set only the 64bit DMA mask on 64bit
architectures, and bails out if it fails. This causes a problem on
some platforms since the 64bit DMA isn't always guaranteed. We should
fall back to the default 32bit DMA when 64bit DMA fails.
Fixes: 6d74b86d3c0f ("ALSA: ctxfi - Allow 64bit DMA")

[bwh: Backported to 3.16:
- Old code was using PCI DMA mask functions
- Deleted error message was different]
