target/sparc/win_helper: silence the compiler warnings
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.
