[PATCH] sound: oss: dmasound: remove software_input_volume declaration

[Gaosheng Cui]

expand_read_bal has been removed since commit fc37449f7959 ("The
next round of scheduled OSS code removal").

software_input_volume has been removed since
commit 0a1b42db4bf9 ("sound: sound/oss/dmasound/: cleanups").

so remove the declare for them from header file.
