db_resync_done lock is used to indicate the amqp thread to wait for resync to
complete. In this case, when we call SchemaTransformer.destroy_instance()
due to Casandra connection failure, this lock remains locked blocking
destroy_instance. destroy_instance calls _vnc_subscribe_callback to drain the
amqp queue which waits infinitely for db_resync_done lock to be released.
This fix releases db_resync_done lock so that destroy_instance doesnt get
blocked.
