Pedro Alvarez f9a2850d74 gnb,ngap: Added interface so the NGAP can pass a NAS message to the RRC 
upon starting the RRC Security Mode command. This allows the gNB to
pass this message only after the SM procedure is complete.

Also made sure that the RRC notifies the NGAP upon the end of the
reconfiguration procedure, to make sure that the NGAP sends the UE
context setup response.
