MdeModulePkg VariableSmm: Check InfoSize correctly
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.
