In original code, zfs_znode_dmu_fini is called in zfs_rmnode without zfs_znode_hold_enter. It seems to assume it's ok to do so when the znode is unlinked. However this assumption is not correct, as zfs_zget can be called by NFS through zpl_fh_to_dentry as pointed out by Christian in https://github.com/openzfs/zfs/pull/12767, which could result in a use-after-free bug.
