irqdomain: Always update revmap when setting up a virq
At irq_setup_virq() time all of the data needed to update the reverse map is available, but the current code ignores it and relies upon the slow path to insert revmap records. This patch adds revmap updating to the setup path so the slow path will no longer be necessary.
