ALSA: ctxfi: cthw20k2: fix mask on conf to allow 4 bits
Currently the mask operation on variable conf is just 3 bits so the switch statement case value of 8 is unreachable dead code. The function daio_mgr_dao_init can be passed a 4 bit value, function dao_rsc_init calls it with conf set to: conf = (desc->msr & 0x7) | (desc->passthru << 3); so clearly when desc->passthru is set to 1 then conf can be at least 8. Fix this by changing the mask to 0xf.
