    drm/xe: Suppress missing outer rpm protection warning
    
    Do not raise a WARN if we are likely within suspending or resuming
    path. This is likely this false positive:
    
    rpm_status:           0000:03:00.0 status=RPM_SUSPENDING
    console:              xe_bo_evict_all (called from suspend)
    xe_sched_job_create:  dev=0000:03:00.0, ...
    xe_sched_job_exec:    dev=0000:03:00.0, ...
    xe_pm_runtime_put:    dev=0000:03:00.0, ...
    xe_sched_job_run:     dev=0000:03:00.0, ...
    rpm_usage:            0000:03:00.0 flags-0 cnt-2  ...
    rpm_usage:            0000:03:00.0 flags-0 cnt-2  ...
    rpm_usage:            0000:03:00.0 flags-0 cnt-2  ...
    console:              xe 0000:03:00.0: [drm] Missing outer runtime
                                                         PM protection
    console:               xe_guc_ct_send+0x15/0x50 [xe]
    console:               guc_exec_queue_run_job+0x1509/0x3950 [xe]
    [snip]
    console:               drm_sched_run_job_work+0x649/0xc20
    
    At this point, BOs are getting evicted from VRAM with rpm
    usage-counter = 2, but rpm status = SUSPENDING.
    
    The xe->pm_callback_task won't be equal 'current' because this call is
    coming from a work queue.
    
    So, pm_runtime_get_if_active() will be called and return 0 because rpm
    status != ACTIVE (but equal SUSPENDING or RESUMING).
    
    v2: Still get the reference even on non suspending/resuming
        path (Jonathan, Brost).
