parport: make lockdep happy with waitlist_lock
parport_unregister_device() should never be used when interrupts are
enabled in hardware and irq handler is registered so there is no need to
disable interrupts when using waitlist_lock. But there is no way to
explain this subtle semantics to lockdep analyzer.
So disable interrupts here too to simplify things. The price is
negligible.
