[PATCH 20.11] crypto/snow3g: fix snow3g enqueue stat increment

[Saoirse O'Donovan <saoirse.odonovan@intel.com>]

The two functions rte_ring_enqueue and rte_ring_enqueue_burst have
different return values which weren't accounted for when updating
enqueue stats. This meant that on success, the enqueued count and
accumulated_enqueued_ops were being incremented by 0.
