nilfs2: fix memory leak in nilfs_sysfs_create_snapshot_group
[ Upstream commit b2fe39c248f3fa4bbb2a20759b4fdd83504190f7 ]
If kobject_init_and_add returns 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.
