mem: Removed circular include ref

If BasicLink.hh is modified, the style checker forces a reordering of
the includes, which results in build errors because it ends up including
Topology.hh before including its xxxParams.hh files, which include
forward declarations of the BasicLink family of classes, and so
Topology.hh throws errors that BasicLink etc. are not declared.
