[PATCH] net/iavf: replace SMP barrier with thread fence

Replace the SMP barrier with atomic thread fence for iavf hw ring scan in the bulk Rx path. This patch introduces a change to the iavf driver that was already added to the i40e driver [1] as part of the adoption of the use of compiler atomics. [1] https://patches.dpdk.org/project/dpdk/patch/20210
