irqchip/stm32: Fix non-SMP build warning
A CONFIG_SMP=n build emits a harmless compile-time warning:
drivers/irqchip/irq-stm32-exti.c:495:12: error: 'stm32_exti_h_set_affinity' defined but not used [-Werror=unused-function]
The #ifdef is inconsistent here, and it's better to use an IS_ENABLED() check
that lets the compiler silently drop that function.
Fixes: 927abfc4461e ("irqchip/stm32: Add stm32mp1 support with hierarchy domain")
