[PATCH] arm64/smp: Remove unused variable irq in arch_show_interrupts()

[Keqian Zhu]

The local variable irq is added in commit a26388152531 ("arm64:
Remove custom IRQ stat accounting"), but forget to remove in
commit 5089bc51f81f ("arm64/smp: Use irq_desc_kstat_cpu() in
arch_show_interrupts()"). Just remove it.
