non-RCU analogue of the previous commit new helper: choose_mountpoint(). Wrapper around choose_mountpoint_rcu(), similar to lookup_mnt() vs. __lookup_mnt(). follow_dotdot() switched to it. Now we don't grab mount_lock exclusive anymore; note that the primitive used non-RCU mount traversals in other direction (lookup_mnt()) doesn't bother with that either - it uses mount_lock seqcount instead.
