In f2fs_init_sysfs(), all failure paths after kset_register() jump to put_kobject, which unconditionally releases both f2fs_tune and f2fs_feat.If kobject_init_and_add(&f2fs_feat, ...) fails, f2fs_tune has not been initialized yet, so calling kobject_put(&f2fs_tune) is invalid. Fix this by splitting the unwind path so each error path only releases objects that were successfully initialized.
