Pierangelo Masarati 9ee9f1e0e1 Reworked again the caching in case of failure.
Now operations that set the status of an entry to CREATING (add.c, modrdn.c)
need to set it to COMMIT, by calling cache_entry_commit, before returning
the entry itself, otherwise the entry is removed from the cache
and its private data is freed.
Should fix crashes due to add failures as in ITS#1245
