Guangshuo Li 745b49c493 f2fs: fix uninitialized kobject put in f2fs_init_sysfs() ...

commit b635f2ecdb upstream.

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.
