SecurityPkg Tcg2Dxe: ASSERT to ensure 'VarData' is not NULL
The logic in functions ReadAndMeasureVariable() and MeasureVariable()
within Tcg2Dxe ensure that 'VarData' will not be NULL before calling
TcgDxeHashLogExtendEvent() at line 1716.
This commit adds ASSERT as warnings for the case that will not happen.
