/*
* brief:
* iterate the raid bdev config and add base bdevs to the raid bdev that
* the config has. Skip nonexistent base bdev but stop iteration and
* return failure if adding base bdev fails.
* Add base bdevs to the raid bdev one by one. Skip any base bdev which doesn't
* exist or fails to add. If all base bdevs are successfully added, the raid bdev
* moves to the configured state and becomes available. Otherwise, the raid bdev
* stays at the configuring state with added base bdevs.
* params:
* raid_cfg - pointer to raid bdev config
* returns:
* 0 - success
* non zero - failure
* 0 - The raid bdev moves to the configured state or stays at the configuring
* state with added base bdevs due to any nonexistent base bdev.
* non zero - Failed to add any base bdev and stays at the configuring state with
* added base bdevs.
