efivarfs: use I_MUTEX_CHILD nested lock to traverse variables on resume
syzbot warns about a potential deadlock, but this is a false positive
resulting from a missing lockdep annotation: iterate_dir() locks the
parent whereas the inode_lock() it warns about locks the child, which is
guaranteed to be a different lock.
So use inode_lock_nested() instead with the appropriate lock class.
