    Fix reserve_block_device_name while attach volume

    The block device name will not be reserved in current implementation
    due to missing volume_id in block_device_mapping. This will cause
    block_device.instance_block_mapping does not return the ebs device
    which should be reserved.

    This patch adds the volume_id to block_device_mapping while reserving
    block device name and changes the rpcapi to send the volume_id.

    Fixes bug 1062033
