sparc64: Disable timer interrupts in fixup_irqs().
When a CPU is offlined, we leave the timer interrupts disabled because fixup_irqs() does not explicitly take care of that case. Fix this by invoking tick_ops->disable_irq(). Based upon analysis done by Paul E. McKenney. Signed-off-by: David S. Miller <davem@davemloft.net>
