Exported per_lcore__rte_errno function to compile ring for windows.
compilation error logs:
librte_ring_rte_ring.c.obj : error LNK2019: unresolved
external symbol per_lcore__rte_errno referenced in
function rte_ring_lookup
The cause was that per_lcore__rte_errno function wasn't included
in the export list.
To solve this per_lcore__rte_errno was added to the Windows export
list.
