net/ixgbe: fix MAC resource leak

In the eth_ixgbevf_dev_init and eth_ixgbe_dev_init functions, memory is
allocated for the MAC address, and the address is stored in the
eth_dev->data->mac_addrs member variable. If the subsequent function is
abnormal, you need to use the rte_free function to release the MAC
address memory.
