fs: use boolean to indicate anonymous mount namespace
Stop playing games with the namespace id and use a boolean instead:
* This will remove the special-casing we need to do everywhere for mount
namespaces.
* It will allow us to use asserts on the namespace id for initial
namespaces everywhere.
* It will allow us to put anonymous mount namespaces on the namespaces
trees in the future and thus make them available to statmount() and
listmount().
