[PATCH -next V2] 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.

Fix it by adding __maybe_unused to dmasound_setup.

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

Fixes: 9dd7c46346ca ("sound/oss/dmasound: fix build when drivers are mixed =y/=m")

Change sinve v1:
 add fixes tag
 use __maybe_unused

This patch is needed in 5.18-rc3 [1] too, should I submit another patch or
you can pick it to the mainstream?
