    sys/vfs/autofs: prevent assert on unmount.
    
    Bring in below commit from NetBSD/autofs. This hasn't existed in
    FreeBSD and DragonFly. This at least avoids potential panic via
    assertion failure on unmount like PR 3062. Note that the assertion
    in autofs_node_delete() is good. There might be mkdir related bug.
