target/sparc/win_helper: silence the compiler warnings

Browse source 
When using -Wimplicit-fallthrough in our CFLAGS, the compiler showed warning:
target/sparc/win_helper.c: In function ‘get_gregset’:
target/sparc/win_helper.c:304:9: warning: this statement may fall through [-Wimplicit-fallthrough=]
  304 |         trace_win_helper_gregset_error(pstate);
      |         ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
target/sparc/win_helper.c:306:5: note: here
  306 |     case 0:
      |     ^~~~

Add the corresponding "fall through" comment to fix it.
