arm64/smp: Remove unused 'irq' variable

From: Arnd Bergmann <[email protected]>

The only use of this variable was removed in a recent patch:

arch/arm64/kernel/smp.c:810:16: error: unused variable 'irq' [-Werror,-Wunused-variable]

                unsigned int irq = irq_desc_get_irq(ipi_desc[i]);

Thanks. I applied Geert's fix already.
