This patch fixes another bug in the dummy_hcd driver.  When a gadget
driver unregisters (simulating a device disconnect), dummy_hcd stops the
timer that it uses for processing outstanding URBs.  Unfortunately this
means that those URBs will never be given back.  The patch lets the timer
continue running; when it expires all the remaining URBs will fail so the
timer won't be reinitialized.
