net/ice: fix data path in secondary process

net/ice: fix data path in secondary process

The rte_eth_devices array is not in share memory, it should not be
referenced by ice_adapter which is shared by primary and secondary.
Any process set ice_adapter->eth_dev will corrupt another process'
context.

The patch removed the field "eth_dev" from ice_adapter.
Now, when the data paths try to access the rte_eth_dev_data instance,
they should replace adapter->eth_dev->data with adapter->pf.dev_data.
