Runtime requests to install an rte_flow with MARK action should fail
if a vector RX function was already chosen for the device during
configuration time.
Currently, i40e rte_flow driver would successfully install the flow
with MARK action, even when vector RX functions are in use. However,
those vector RX functions will fail to retrieve the MARK data from the
device descriptor into the mbuf. The original app installing the flow
would never know what went wrong. The change introduced in this patch
must be reverted if/when vector RX functions start supporting correct
FDIR processing for MARK actions.

We may not need to prevent this if the device is already stopped (check dev->data->dev_started),
since with the fdir flow be created here, vector path will not be selected in following dev_start.

Makes sense, sending a v2 in a bit.
