MR !1434 ULINFO cleanup
- This struct is used to store the uplink 5G nFAPI messages between the
  proxy and the gNB MAC layer. The original OAI implementation utilizes
  a similarly named variable (UL_info) to store the uplink 5G nFAPI
  messages between the PHY and MAC layer. This commit will utilize the
  original UL_info variable prior to calling the handle functions. These
  changes allow us to make minimal changes to the nFAPI handle functions
  and modifies the NR_UL_Indication parent function instead.
