[PATCH] (2/22) compile fixes for dmsound (static vs. extern)

[Al Viro]

sound/oss/dmasound/dmasound_atari.c has static expand_bal
sound/oss/dmasound/dmasound_q40.c has static expand_bal
sound/oss/dmasound/dmasound_awacs.c has non-static expand_bal
sound/oss/dmasound/trans_16.c uses expand_bal from dmasound_awacs.c
all 4 include dmasound.h; extern for expand_bal used to be there,
which is a bloody bad idea, considering _atari and _q40.  Moved the
extern to trans_16.c.
