ctdb-protocol: CID 1499395: Uninitialized variables (UNINIT)

Browse Source 
Issue is reported here:

853     	case CTDB_CONTROL_DB_VACUUM: {
854     		struct ctdb_db_vacuum db_vacuum;
855
>>>     CID 1499395:  Uninitialized variables  (UNINIT)
>>>     Using uninitialized value "db_vacuum.full_vacuum_run" when calling "ctdb_db_vacuum_len".
856     		CHECK_CONTROL_DATA_SIZE(ctdb_db_vacuum_len(&db_vacuum));
857     		return ctdb_control_db_vacuum(ctdb, c, indata, async_reply);
858     	}

The problem is that ctdb_bool_len() unnecessarily dereferences its
argument, which in this case is &db_vacuum.full_vacuum_run.  Not a
security issue because the value copied by dereferencing is not used.
