[PATCH v2] net/ixgbe: fix ixgbe firmware version inconsistency

[Shiyang He <shiyangx.he@intel.com>]

This patch follows the code of ixgbe kernel driver so that it keeps the
firmware version obtained by dpdk-ethtool consistent with that obtained
by linux-ethtool.

Fixes: 8b0b56574269 ("net/ixgbe: add firmware version get")
