s5p-mfc: use MFC_BUF_FLAG_EOS to identify last buffers in decoder capture queuefor-4.4
MFC driver never delivered EOS event to apps feeding constantly its capture buffer with fresh buffers. The patch fixes it by marking last buffers returned by MFC with MFC_BUF_FLAG_EOS flag and firing EOS event on de-queuing such buffers.
