UefiPayloadPkg/UefiPayloadEntry: Fix memory corruption 

UefiPayloadEntry's AllocatePool() applies the "sizeof" operator to
HOB index rather than the HOB header structure. This yields 4 Bytes
compared to the 8 Bytes the structure header requires. Fix the call
to allocate the required space instead.
