In response to "usbip detach -p [port_number]" user command,vhci_shoutdown_connection gets executed which kills tcp_tx,tcp_rx kernel threads and then vhci_device_reset resets all usb_device struct variables except kernel thread pointers. so, at the time of vhci_hcd removal vhci_shoutdown_connection tries to kill kernel threads which are already killed.
