usb-hcd-xhci: Remove unused cancelled member from XHCITransfer 

Since qemu's USB model is geared towards emulated devices cancellation
is instanteneous, so no need to wait for cancellation to complete, as
such there is no wait for cancellation code, and the cancelled bool
as well as the bogus comment about it can be removed.
