I think you are missing some cases in lookup where you should add
SAVENAME flag. I'd start from adding this (or similar) assertions:

	KASSERT((ap->a_cnp->cn_flags & SAVENAME), ("No SAVENAME"));

to the following functions:

	tmpfs_create()
	tmpfs_remove()
	tmpfs_mkdir()
	tmpfs_rmdir()
	tmpfs_rename() (assert both: fcnp and tcnp)
	tmpfs_symlink()
	tmpfs_link()
