Dongliang Mu 7923c77f8f UPSTREAM: fs: erofs: add sanity check for kobject in erofs_unregister_sysfs 
Syzkaller hit 'WARNING: kobject bug in erofs_unregister_sysfs'. This bug
is triggered by injecting fault in kobject_init_and_add of
erofs_unregister_sysfs.

Fix this by adding sanity check for kobject in erofs_unregister_sysfs

Note that I've tested the patch and the crash does not occur any more.
