The code in xskq_produce_addr erroneously checked if there was up to LAZY_UPDATE_THRESHOLD amount of space in the completion queue. It only needs to check if there is one slot left in the queue. This bug could under some circumstances lead to a WARN_ON_ONCE being triggered and the completion message to user space being lost.
