db_redis: Fix scanning large tables

* When querying large tables (e.g. pre-loading location by usrloc),
  make sure to use O(1) when adding keys by prepending them to list.
* Increase batch size of redis scan command to reduce number of
  redis queries.
* Batch creation of DB_ROW entries to free up memory allocated by
  redis in heap regularly.
* Fix more issues reported by coverity.
