ShellPkg: smbiosview - print field values as unsigned integers

Posted by Rebecca Cran 4 years ago

This prevents overflow when printing DWORD fields such as the type 17
tables's extended DIMM size.

Similar issue with type 14:

         ShellPrintEx(-1,-1,L"ItemType %d: %d\n", Index + 1, 
Struct->Type14->Group[Index].ItemType);

         ShellPrintEx(-1,-1,L"ItemHandle %d: %d\n", Index + 1, 
Struct->Type14->Group[Index].ItemHandle);
