nfp: initialize netdev's dev_port with correct id
`dev_port` is used to differentiate devices that instantiate from
the same function, which is the case in most of NFP NICs.
In some customized scenario, `dev_port` is used to rename netdev
instead of `phys_port_name`. Example rules using `dev_port`:
SUBSYSTEM=="net", ACTION=="add", KERNELS=="0000:e1:00.0", ATTR{dev_port}=="0", NAME:="ens8np0"
SUBSYSTEM=="net", ACTION=="add", KERNELS=="0000:e1:00.0", ATTR{dev_port}=="1", NAME:="ens8np1"
To take port split case into account, here we initialize `dev_port`
according to the port sequence in eth_table from management firmware
instead of using port label id directly. And management firmware
makes sure that port sequence matches its label id.
