usbip: vhci_hcd: fix calling usb_hcd_giveback_urb() with irqs enabled
kcov testing uncovered call to usb_hcd_giveback_urb() without disabling
interrupts.
Link: https://lore.kernel.org/linux-usb/CAAeHK+wb4k-LGTjK9F5YbJNviF_+yU+wE_=Vpo9Rn7KFN8vG6Q@mail.gmail.com/
usb_hcd_giveback_urb() is called from vhci's urb_enqueue, when it
determines it doesn't need to xmit the urb and can give it back.
This path runs in task context.
Disable irqs around usb_hcd_giveback_urb() call.
