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.

Removing the memset seemed to hide the problem
and now the problem is appearing in a differnt
manner... it is causing the NRUE to skip HARQ
PIDs as its filling the UCI indication and process
the DCI PDUs. So adding the memset causes the NR UE
to crash becasue the DL_BWP_ID is becoming 0
which leads us to index into an pointer that is not
allocated and then a crash happens in DCI handling.

This requires some updates to the nFAPI code as well.
We also have declared the def_dci_rel15 extern variable
consistently throughout the code.

In this commit, the gNB is still crashing. However, it seems
that the NSA UE is sending the proper responses back, but there
some sort of incorrect management of the def_dci_pdu_rel15
variable. If we memset this array to 0, we can see incorrect
0 assignments to elements of the UCI indications. Hopefully
fixing this issue will result in less gNB crashes.

Also, removing memset for def_dci_pdu_rel15 because
it is setting the DL_BWP_ID = 0 before we have used
it.

1. If matched rnti does not exist between crc_ind pdus and rx_ind puds, the ind or unmatched pdus will be requeued.
2. Sending crc_ind and rx_ind togetehr with crc_ind first in nrUE.
