    drm/xe/xe-for-ci: Check whether oom was due to ww mutex error injection
    
    When CONFIG_DEBUG_WW_MUTEX_SLOWPATH is enabled, which it is in CI, but
    not in production kernels, an injected -EDEADLK error will, due to
    limitations in TTM, cause false OOM notifications.
    
    Check whether the OOM was likely caused by an -EDEADLK injection and in
    that case, rerun the validation.
