Fixed the buffer constructor called with a pair of iterators.
The current implementation has a problem due to ambiguous spec.
The buffer should never write back data unless there is a call to set_final_data(), but the current implementation does it.
I corrected the spec in KhronosGroup/SYCL-Docs#76.
So, now we can change the buffer implementation according to the clarified spec.
The test case buffer.cpp also needed change because of this change.
The user should not expect the automatic write-back of data upon destruction of buffer.
