x86/irq: Validate that irq descriptor is still active
commit 36f34c8c63da3e272fd66f91089228c22d2b6e8b upstream.
In fixup_irqs() we unconditionally dereference the irq chip of an irq
descriptor. The descriptor might still be valid, but already cleaned up,
i.e. the chip removed. Add a check for this condition.
