Subject: [PATCH 15/43] usb-hcd-xhci: Remove unused cancelled member from
XHCITransfer

O-Subject: [RHEL-7.1 qemu-kvm PATCH 16/37] usb-hcd-xhci: Remove unused cancelled member from XHCITransfer
Bugzilla: 980747

From: Hans de Goede <hdegoede@redhat.com>
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.
