Jian J Wang 41b4600c30 MdeModulePkg/DxeIplPeim: fix incorrect page table split during protecting
The root cause of this issue is that, during splitting page table, the page
size should be the value of next level (smaller one) instead of current level.
The wrong page size will then cause wrong page table introduced, which will
break the normal boot.

Validation works include booting to Windows 10 and Fedora 26 on real Intel
platform and OVMF emulated platform in addition to manual checks on page
table with JTAG tool.
