[PATCH iproute2-next] devlink: Show port state values in man page and in the help command

[Parav Pandit <parav@nvidia.com>]

Port function state can have either of the two values - active or
inactive. Update the documentation and help command for these two
values to tell user about it.

With the introduction of state, hw_addr and state are optional.
Hence mark them as optional in man page that also aligns with the help
command output.
