Inside of passing the RRCReconfiguration buffer, call RRCReconfiguration message generation inside the F1 callback. This will simplify the code in the rrc_CU_process_ue_context_setup_response() function once the N2 handover case is introduced. In rrc_CU_process_ue_context_setup_response(), with presence of the HO context, the HO ACK callback is called only once and depending on the type of HO it will do either RRCReconfiguration for F1 and HandoverCommand for N2.
