Chris Wilson a5cae7b8ed drm/i915/breadcrumbs: Disable interrupt bottom-half first on idling 
Before walking the rbtree of waiters (marking them as complete and waking
them), decouple the interrupt handler. This prevents a race between the
missed waiter waking up and removing its intel_wait (which skips
checking the lock) and the interrupt handler dereferencing the
intel_wait. (Though we do not expect to encounter waiters during idle!)

Fixes: e1c0c91bda ("drm/i915: Wake up all waiters before idling")
