A reset requested through /sys/bus/pci/devices/.../reset invokes the driver reset_prepare() and reset_done() callbacks. The QAT driver does not implement those callbacks today, so the reset proceeds without quiescing the device or bringing it back up afterward, which leaves the device unusable. Hook reset_prepare() and reset_done() into adf_err_handler so the common shutdown and recovery flow also runs for reset. Skip device quiesce if the device is already in a down state.
