Subject: [PATCH 2/3] irq/irq_sim: modify the return value check for irq_sim_init()

As discussed with Marc Zyngier: irq_sim_init() and its devres variant
should return the base of the allocated interrupt range on success
rather than 0. This will be modified later - first, change the way
devm_irq_sim_init() check the return value.
