x86/irq: Make irq activate operations symmetric
The recent commit which prevents double activation of interrupts unearthed
interesting code in x86. The code (ab)uses irq_domain_activate_irq() to
reconfigure an already activated interrupt. That trips over the prevention
code now.
Fix it by deactivating the interrupt before activating the new configuration.
Fixes: 08d85f3ea99f1 "irqdomain: Avoid activating interrupts more than once"
