Bartosz Golaszewski 28b6afa7d4 genirq/irq_sim: Check the return value of irq_sim_init() for error codes
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.

Make devm_irq_sim_init() check for an error code. This is a preparatory
change for modifying irq_sim_init() itself.
