[dpdk-stable] [PATCH] lib/ring: fix the bug of HTS/RTS bulk enqueue

[Feifei Wang]

Directly call "_rte_ring_do_enqueue_elem" function can result in the
process skips the "switch" order and cannot call the APIs of RTS and HTS
mode in "rte_ring_enqueue_bulk_elem" function.

To fix it, remove the unnecessary function and make
"_rte_ring_do_enqueue_elem" consistent with "_rte_ring_do_dequeue_elem".

Fixes: e6ba4731c0f3 ("ring: introduce RTS ring mode")
