nfp: ethtool: fix the display error of ethtool -m DEVNAME

Browse Source 
commit 4ae97cae07e15d41e5c0ebabba64c6eefdeb0bbe upstream.

The port flag isn't set to `NFP_PORT_CHANGED` when using
`ethtool -m DEVNAME` before, so the port state (e.g. interface)
cannot be updated. Therefore, it caused that `ethtool -m DEVNAME`
sometimes cannot read the correct information.

E.g. `ethtool -m DEVNAME` cannot work when load driver before plug
in optical module, as the port interface is still NONE without port
update.

Now update the port state before sending info to NIC to ensure that
port interface is correct (latest state).
