integration fix: let dlsim and ulsim work again

There is now the function copy_harq_proc_struct and some
procedures for the UE have changed, which makes necessary
to have UE->dlsch valid for both subframes (odd and even).

We increase memory usage, maybe it's not the correct solution.
To be kept in mind if something goes wrong at some point.
