[PATCH] arm64: smp: remove unused variable

[Wolfram Sang]

Not used anymore after refactoring:

arch/arm64/kernel/smp.c: In function ‘arch_show_interrupts’:
arch/arm64/kernel/smp.c:810:16: warning: unused variable ‘irq’ [-Wunused-variable]
  810 |   unsigned int irq = irq_desc_get_irq(ipi_desc[i]);

Fixes: 5089bc51f81f ("arm64/smp: Use irq_desc_kstat_cpu() in arch_show_interrupts()")
