USB: usbip: clean up mixed use of _irq() and _irqsave()
It generally doesn't make sense to use _irq() and _irqsave() in the same
function because either some of the callers have disabled IRQs or they
haven't. In this case, the v_recv_cmd_submit() appears to always be
called with IRQs enabled so the code works fine. That means I could
convert it to either _irq() or _irqsave() but I chose to use _irqsave()
because it's more conservative and easier to review.
