When requeueing deferred URXEs retain the order

If a URXE cannot be processed yet then we add it to the urx_deferred list.
Later, when they can be processed, we requeue them in the urx_pending list.

We must not reverse the order when doing so. We want to process the URXEs
in the order that they were received.
