Ilia Levi 4d79a1266d drm/xe: Make irq enabled flag atomic ...

The irq.enabled flag was protected by a spin lock (irq.lock).
By making it atomic we no longer need to wait for the spin lock in
irq handlers. This will become especially useful for MSI-X irq
handlers to prevent lock contention between different interrupts.
