ALSA: sparc/dbri: add missing fallthrough

Fixes compiler error with probably newer compilers:

sound/sparc/dbri.c:595:2: error: unannotated fall-through between switch labels [-Werror,-Wimplicit-fallthrough]
  595 |         case 1:
      |         ^
sound/sparc/dbri.c:595:2: note: insert 'break;' to avoid fall-through
  595 |         case 1:
      |         ^
      |         break;
