This bug was introduced in commit b3527dedc395 ("MdeModulePkg/DxeIpl: Create 5-level page table for long mode", 2019-08-09). It's being addressed in the following (pending) patch: [edk2-devel] [PATCH 1/1] MdeModulePkg/DxeIplPeim: Relocate the operation of PageMapLevel5Entry++ (I'm calling the issue a bug and not an invalid compiler warning because the patch looks like an actual fix.)
