Subject: [Patch edk2-platforms] IntelSiliconPkg/IntelVTdDxe: Fix CLANG detected
incorrect return
CreateSecondLevelPagingEntryTable() has a return type of
VTD_SECOND_LEVEL_PAGING_ENTRY * and an error condition returns a value of NULL.
Change return value of EFI_SUCCESS (value 0) to NULL to address CLANG compiler
detection of incorrect return type.
