s4-dsdb_schema: Seize using global_schema when referencing new schema for an LDB

Without this change, when a schema is set to ldb, the
effect is that dsdb_get_schema() returns global_schema
preferably.

Thus we end up with two schemas in effect:
- global one, which is the old one and it is still used everywhere
- new one, which is just cached in ldb, but can't be used, as
  there is no way to access it
