[PATCH] arm: smp: remove unused variable

[Wolfram Sang]

Not used anymore after refactoring:

arch/arm/kernel/smp.c: In function ‘show_ipi_list’:
arch/arm/kernel/smp.c:543:16: warning: variable ‘irq’ set but not used [-Wunused-but-set-variable]
  543 |   unsigned int irq;

Fixes: 88c637748e31 ("ARM: smp: Use irq_desc_kstat_cpu() in show_ipi_list()")
