Yichong Chen d708f17213 usbip: tools: support SuperSpeedPlus devices 
commit 195e667c87 upstream.

USB devices running at SuperSpeedPlus report "10000" or "20000" in
their sysfs speed attribute. usbip currently maps only "5000" to
USB_SPEED_SUPER, so a SuperSpeedPlus device is imported as
USB_SPEED_UNKNOWN.

The attach request is then rejected by vhci_hcd:

  vhci_hcd: Failed attach request for unsupported USB speed: UNKNOWN

Map the SuperSpeedPlus sysfs speed values to USB_SPEED_SUPER_PLUS, use
the SuperSpeed VHCI hub for SuperSpeedPlus devices, and recognize the
gadget current_speed string used by the kernel.

Fixes: b2316645ca ("usb: show speed "10000" in sysfs for USB 3.1 SuperSpeedPlus devices")
