switchdev: Adding complete operation to deferred switchdev ops
When using switchdev deferred operation (SWITCHDEV_F_DEFER), the operation is executed in different context and the application doesn't have any way to get the operation real status. Adding a completion callback fixes that. This patch adds fields to switchdev_attr and switchdev_obj "complete_priv" field which is used by the "complete" callback. Application can set a complete function which will be called once the operation executed.
