IntelSiliconPkg IntelVTdDxe: Fix potential NULL pointer dereference
The implementation of MdeModulePkg\Universal\Acpi\AcpiTableDxe reserves
first entry of RSDT/XSDT to FADT, the first entry value is 0 when FADT
is not installed. So the RSDT/XSDT parsing code should check the entry
value first before checking the table signature.
