[spice-gtk v3 08/16] file-xfer: fix progress info on cancelled transfers

[Victor Toso <victortoso@xxxxxxxxxx>]

Application can start multiple file-transfers in one operation and
cancel a few of them while the operation is ongoing. In that case, we
should remove the file-size of the transfer operation otherwise we
will send incorrect progress data.

Taking in consideration the split of SpiceFileTransferTask, this patch
includes spice_file_transfer_task_get_file_size() internal helper
function.
