[PATCH BlueZ] mesh: Re-arrange Join/Create/Import/Attach page saving

[PATCH BlueZ] mesh: Re-arrange Join/Create/Import/Attach page saving

[Brian Gix]

When an App is creating or attaching to a node, it first evaluates the
validity of the Apps composition. Invalid compositions are not allowed
to continue.  Valid compositions need to be saved, which means that
create_node_config() must be called as part of Composition validation.
