nfp: improve link modes reading process
Avoid reading link modes from management firmware every time when
`ethtool_get_link_ksettings` is called, only communicate with
management firmware when necessary like we do for eth_table info.
This change can ease the situation that when large number of vlan
sub-interfaces are created and their information is requested by
some monitoring process like PCP [1] through ethool ioctl frequently.
