genirq/irqdomain: Rename early argument of irq_domain_activate_irq()

The 'early' argument of irq_domain_activate_irq() is actually used to
denote reservation mode. To avoid confusion, rename it before abuse
happens.

No functional change.

Fixes: 72491643 ("genirq/irqdomain: Update irq_domain_ops.activate() signature")
