Also, the ul_slot was not properly wrapping.
It was increased to a value greater than the
largest slot value.

But, we are not going to process the tx_request
unless we are waiting for the RAR OR if the RNTI
from the previous DCI matches.

In this commit, we create a new flag in the MAC
instance which is set to true if the recevied
DL DCI PDU's RNTI value matches the current UEs
RNTI value. If the RNTI value does not match,
then we should not process the recevied tx_request.
This check should only take place after the CFRA
procedure is complete.

Previously, we thought that filling the UCI ind
after we got the pdsch payload would stop the
 harq_pid from going inactive, but this was not
the case. The harq_pid is getting set to inactive
too early because of the sf_slot ahead value. The
fix for this will come in the next commit.

The harq_pid is set to inactive during the scheduling
of ACK/NACK, but this is happening before tx_req (PDSCH)
is recevied. We update the global harq_pid then use it
once we get the PDSCH PDU, then we set it to inactive.
Also, the global previously wasnt being set properly because
a memset was changing the def_dci_re15 struct. We now
memset after we update the harq_pid global.

In this commit, we introduced a new global to save
the harq_pid from the PDCCH that comes down in the
DCI message so that we can use the harq_pid in the
PDSCH. Now, the UCI ind will be filled after we
have recevied the PDSCH in the tx_request.

Previously, the ue_id passed into the
init_pdcp() in  the proxy would be 41.
This is outside of the bounds of the
nas_sock_fd array and would cause a crash.
This was occuring because the node_number
in the NRUE starts at 2, not 1.
