[PATCH spice-gtk] Spicy: cancel file transfer when dialog is closed

[Jonathon Jongsma <jjongsma@xxxxxxxxxx>]

Clicking the 'X' to close the file transfer dialog did not actually
cancel the ongoing file transfer, and resulted in a bunch of critical
warnings on the terminal. Make the delete-event explicitly cancel all
ongoing file transfers.
