nilfs2: fix memory leak in nilfs_sysfs_create_##name##_group
[ Upstream commit 24f8cb1ed057c840728167dab33b32e44147c86f ]
If kobject_init_and_add return with error, kobject_put() is needed here to
avoid memory leak, because kobject_init_and_add may return error without
freeing the memory associated with the kobject it allocated.
