Before this patch, the progress_callback is being called from
SpiceFileTransferTask each time that some data is flushed to the agent
of this given xfer-task. The progress value is computed by iterating
on all available xfer-tasks.
This patch intend to fix/change:
* The progress_callback should be called only with information related
to the FileTransferOperation of given xfer-task; This was also
suggested by 113093dd00a1cf10f6d3c3589b7589a184cec081;
* The progress_callback should not be done from SpiceFileTransferTask
context by (proposed) design. As the transfer operation starts in
spice_main_file_copy_async(), FileTransferOperation should handle
these calls.
