[dpdk-dev] [PATCH] ring: fix return value for single dequeue function

[Bruce Richardson]

The error return code for rte_ring_dequeue() function should be -ENOENT
rather than -ENOBUFS (which is the error value from the enqueue() fn).

Fixes: cfa7c9e6fc1f ("ring: make bulk and burst return values consistent")
