portcls: CPortPinWavePci::HandleKsStream handles wrongly m_capture flag

http://doxygen.reactos.org/d3/dda/pin__wavepci_8cpp_source.html#l00543
As you can see, the function CPortPinWavePci::HandleKsStream handles m_capture==False and m_Capture=True in the same way.

00559 if (m_Capture)
00560 m_Position.WriteOffset += Data;
00561 else
00562 m_Position.WriteOffset += Data;
