This patch fixes a kernel panic that can occur when disconnecting a wireless USB->serial device. When the serial device disconnects, the device cleanup procedure ends up calling usb_hcd_disable_endpoint on the serial device's endpoints. The wusbcore uses the ABORT_RPIPE command to abort all transfers on the given endpoint but it does not properly give back the URBs when the transfer results return from the HWA. This patch prevents the transfer result processing code from bailing out when it sees a WA_XFER_STATUS_ABORTED result code so that these urbs are flushed properly by usb_hcd_disable_endpoint. It also updates wa_urb_dequeue to handle the case where the endpoint has already been cleaned up when usb_kill_urb is called which is where the panic originally occurred.
