Remove Size==0 branch in SmmAllocatePool()

The background is :

The SmmMemoryAllocationLib of one of the instance of MemoryAllocation library class. As in MdePkg comment for AllocatePool() : “If AllocationSize is 0, then a valid buffer of 0 size is returned.”,the SMM library implements AllocatePool by SMST service SmmAllocatePool which does NOT support the zero size.
