In nvme_ctrlr_hw_reset(), if we encounter a controller whose CC.EN bit is already 0 (controller is disabled), the previous code would enable the controller just so that it could be disabled to get a full reset (transition from CC.EN = 1 to CC.EN = 0). However, it is a safe assumption that if CC.EN is already 0, the controller has just been reset, so we don't need to reset it again. This saves a significant amount of time (2+ seconds per controller with Intel SSD DC P3700) during initialization for devices that were disabled on startup.
