[Intel-gfx] [PATCH] gpu/drm/i915: disable interrupt when holding spinlock

The irq_lock is acquired in multiple functions: 1) i915_request_cancel_breadcrumb <- ... <- panfrost_gpu_irq_handler 2) intel_engine_breadcrumbs_irq <- ... <- cherryview_irq_handler 3) i915_request_enable_breadcrumb 4) virtual_xfer_breadcrumbs The former two functions are reachable from IRQ
