usb: wusbcore: remove excessive irqsave

wa_urb_dequeue() locks multiple spinlocks while disabling interrupts:

   spin_lock_irqsave(&lock1, flags);
   spin_lock_irqsave(&lock2, flags2);

Obviously there is no need for the second irqsave and "flags2" variable
since interrupts are disabled at that point. Remove the second irqsave:

   spin_lock_irqsave(&lock1, flags);
   spin_lock(&lock2);

and eliminate the flags2 variable.
