def_dci_pdu_rel15 fix.

In this commit we were trying to understand why
the memset of the def_dci_pdu_rel15 array in the NRUE
was casuing the NR UE to crash. This was happening
becuase some of the members of the def_dci_pdu_rel15
array canont be zero in NSA mode. This was happening
because sometimes, we would recevied two DCI indications
in a row, after the first one, we would be memesetting
the array to all 0s and then try to process the second
DCI. The fix we have implemnted is to call the configure_dci()
prior to processing ANY DCI, to ensure we have properly
configured the UE to handle these DCIs.

Also, in the gNB, it was not able to find the UL scheduled
slot for the feedback harq because it was not accounting for
the slot wrapping.
