The preivous commit 8fd0c1b0647a ("nilfs2: fix memory leak in nilfs_sysfs_delete_device_group") only handles the memory leak in the nilfs_sysfs_delete_device_group. However, the similar memory leak still occurs in the nilfs_sysfs_create_device_group.
Fix it by adding kobject_del when kobject_init_and_add succeeds, but one of the following calls fails.
