amdgpu_get_xgmi_hive() increases the kobject reference counter of the hive it returned. The hive returned by amdgpu_get_xgmi_hive() should be released with the help of amdgpu_put_xgmi_hive() to balance its kobject reference counter properly. Forgetting the amdgpu_put_xgmi_hive() operation will result in reference leak. We can fix it by calling amdgpu_put_xgmi_hive() before the end of the function.
