The bdev hot remove might be an async process. The bdev_open will return an error during the hot remove process. If someone invoke the bdev_get_bdevs API when a bdev is in the middle of a hot remove process, the spdk_for_each_bdev function will stop its loop when a bdev_open return an error. Thus the bdev_get_bdevs will only return partual bdevs or even return an empty list if the hot remove bdev is the first bdev in the loop. When spdk_for_each_bdev and spdk_for_each_bdev_leaf loop for each bdevs, if a bdev returns an error, we skip that bdev instead of stop the whole loop.
