The SmmLockBox driver in
"MdeModulePkg/Universal/LockBox/SmmLockBox/SmmLockBox.inf" currently
specifies a DepEx on EFI_SMM_SW_DISPATCH2_PROTOCOL.
However, the driver doesn't use this protocol at all, either directly or
indirectly. It calls SmiHandlerRegister()
[MdeModulePkg/Core/PiSmmCore/Smi.c] to register SmmLockBoxHandler()
(which serves LockBox requests).
In turn, the SMM Core function SmiHandlerRegister() is also implemented
without EFI_SMM_SW_DISPATCH2_PROTOCOL.
The DepEx has been present since the initial commit of the SmmLockBox
driver (SVN r12029); it is probably superfluous. Let's remove it.
(Alternatively, we could extend OvmfPkg/EmuSmmDxe to fake this protocol,
and return EFI_UNSUPPORTED when any member is called.)

2. Add check to ensure CommBufferPayloadSize not exceed mVariableBufferPayloadSize or is enough to hold function structure in VariableSmm and FtwSmm.
3. Align FtwGetLastWrite() in FaultTolerantWriteSmmDxe.c to FtwGetLastWrite() in FaultTolerantWrite.c.
