genirq: Fix incorrect proc spurious output
commit 25c9170ed64a6551beefe9315882f754e14486f4 upstream. Since commit a1afb637(switch /proc/irq/*/spurious to seq_file) all /proc/irq/XX/spurious files show the information of irq 0. Current irq_spurious_proc_open() passes on NULL as the 3rd argument, which is used as an IRQ number in irq_spurious_proc_show(), to the single_open(). Because of this, all the /proc/irq/XX/spurious file shows IRQ 0 information regardless of the IRQ number. To fix the problem, irq_spurious_proc_open() must pass on the appropreate data (IRQ number) to single_open().
