[lvc-project] [PATCH] ksmbd: zero the object ID before filling FS_OBJECT_ID_INFORMATION

[ChenXiaoSong]

Should we clear `info`? Will `info->extended_info.version_string` also leak?

```
7437         case FS_OBJECT_ID_INFORMATION:
7438         {
7439                 struct object_id_info *info;
7440
7441                 info = (struct object_id_info *)(rsp->Buffer);
...
7454                 memcpy(info->extended_info.version_string, "1.1.0", 
strlen("1.1.0"));
7455                 rsp->OutputBufferLength = cpu_to_le32(64);
...
7458         }
```
