REF: https://bugzilla.tianocore.org/show_bug.cgi?id=290 Current SmmVariableGetStatistics() in VariableSmm.c is always checking input InfoSize against the first variable info, it is incorrect. For instance, there are three variables. BootOrder Boot0000 Boot0001 If the input InfoEntry is holding the second variable info (Boot0000) and InfoSize is sizeof (VARIABLE_INFO_ENTRY) + StrSize (L"Boot0000"), current code will return EFI_BUFFER_TOO_SMALL, but it should return the third variable info (Boot0001). This patch is to refine the code logic.
