sound/oss: fix sparse warnings: different signedness
Impact: Change signature of 'set_volume_stereo' and 'set_volume_mono'.
Fix this sparse warnings:
sound/oss/pss.c:545:42: warning: incorrect type in argument 2 (different signedness)
sound/oss/pss.c:546:42: warning: incorrect type in argument 3 (different signedness)
sound/oss/pss.c:554:59: warning: incorrect type in argument 2 (different signedness)
sound/oss/pss.c:560:59: warning: incorrect type in argument 2 (different signedness)
sound/oss/pss.c:566:59: warning: incorrect type in argument 2 (different signedness)
