Dan Carpenter 62e4efe337 usbip: vudc: Don't enable IRQs prematurely
This code does:

	spin_unlock_irq(&udc->ud.lock);
	spin_unlock_irqrestore(&udc->lock, flags);

which does not make sense.  In theory, the first unlock could enable
IRQs and then the second _irqrestore could disable them again.  There
would be a brief momemt where IRQs were enabled improperly.

In real life, however, this function is always called with IRQs enabled
and the bug does not affect runtime.
