[PATCH -next] sound/oss/dmasound: fix 'dmasound_setup' defined but not used

[Miles Chen]

We observed: 'dmasound_setup' defined but not used error with
COMPILER=gcc ARCH=m68k DEFCONFIG=allmodconfig build.

__setup() does not work if MODULE is defined.
Fix it by warpping dmasound_setup with #ifndef MODULES.

Error(s):
sound/oss/dmasound/dmasound_core.c:1431:12: error: 'dmasound_setup' defined but not used [-Werror=unused-function]
