Subject: [PATCH] sparc64: uprobes: add missing break

Missing fallthrough causes failure with newer compilers:

arch/sparc/kernel/uprobes.c:284:2: error: unannotated fall-through between switch labels [-Werror,-Wimplicit-fallthrough]
  284 |         default:
      |         ^
arch/sparc/kernel/uprobes.c:284:2: note: insert 'break;' to avoid fall-through
  284 |         default:
      |         ^
      |         break;
