Dapeng Yu 435d523112 net/iavf: fix multi-process shared data 
When the iavf_adapter instance is not initialized completely in the
primary process, the secondary process accesses its "rte_eth_dev"
member, it causes secondary process crash.

This patch replaces eth_dev with eth_dev_data in iavf_adapter.

Fixes: f978c1c9b3 ("net/iavf: add RSS hash parsing in AVX path")
Fixes: 9c9aa00403 ("net/iavf: add offload path for Rx AVX512 flex descriptor")
Fixes: 63660ea3ee ("net/iavf: add RSS hash parsing in SSE path")
