[dpdk-dev] [PATCH] net/i40e: fix setting MAC address on i40evf

[Beilei Xing]

New mac address is copied to dev->data->mac_addrs[0]
before calling setting MAC address ops. So it will fail
when deleting dev->data->mac_addrs[0].
Deleting hw->mac.addr will fix the issue.

Fixes: 943c2d899a0c ("net/i40e: set VF MAC from VF")
