Log Message:
-----------
UefiCpuPkg/CpuPageTableLib: Init local variable before using it.
The local variable OneOfPagingEntry is used before initialized, this
may cause reserved bit in page table entry is set especially in PAE
paging mode. The bug is random because it depends on the value in
stack.
