commit 0051163ab3d8090a08ea2ea5edbb738c0920000a
Author: Chris Wilson <chris@chris-wilson.co.uk>

    drm/i915/execlists: Always clear preempt status on cancelling all
    
    On reset/wedging, we cancel all pending replies from the HW and we also
    want to cancel an outstanding preemption event. Since we use the same
    function to cancel the pending replies for reset and for a preemption
    event, we can simply clear the active tracking for all.
    
    v2: Keep execlists_user_end() markup for wedging
    v3: Move assignment to inline to hide the bare assignment.
    
    Fixes: 60a943245413 ("drm/i915/execlists: Drop clear_gtiir() on GPU reset")
