Tail load in __rte_ring_move_cons_head and __rte_ring_move_prod_head
can be changed to __ATOMIC_RELAXED from __ATOMIC_ACQUIRE.
Because to calculate the addresses of the dequeue
elements __rte_ring_dequeue_elems uses the old_head updated by the
__atomic_compare_exchange_n intrinsic used in
__rte_rin
