    usb: xhci: fix spinlock recursion for USB2 test mode
    Peter Chen authored and Greg Kroah-Hartman committed 
    Both xhci_hub_control and xhci_disable_slot tries to hold spinlock, the
spinlock recursion occurs when enters USB2 test mode. Fix it by unlock
spinlock before calling xhci_disable_slot.
