ice: support subfunction devlink Tx topology

Flow for creating Tx topology is the same as for VF port representors,
but the devlink port is stored in different place (sf->devlink_port).

When creating VF devlink lock isn't taken, when creating subfunction it
is. Setting Tx topology function needs to take this lock, check if it
was taken before to not do it twice.
