In addition to hotplug events, the kernel may also mark a failing vdev as REMOVED. This was observed in a customer report and reproduced by forcing the NVMe host driver to disable the device after a failed reset due to command timeout. In such cases, the spare was not activated because the device had already transitioned to a REMOVED state before zed processed the event. To address this, explicitly attempt hot spare activation when the kernel marks a device as REMOVED.
