db_redis: don't leave unconsumed redis replies in case of error on update

Execute db_redis_consume_replies on failed update same as in db_redis_insert:
if db_redis_perform_update encounters an error it was leaving unconsumed data
thus causing unexpected reply later on when reading from the same connection.
