net_shaper: remove incorrect comment about group leaves

It is true that the user-facing group() operation can only
be invoked with queues as leaves (see net_shaper_parse_leaf()),
but the driver facing op is also called when we delete a node.
When we delete a node we conceptually call

    group(parent, node.list_of_leaves)

to add node's leaves to the parent. Node deletion "mid-hierarchy"
is supported so some of the leaves may themselves be nodes.
Therefore the driver facing group() may be called with nodes.

Remove the incorrect comment, and add a comment about differences
between the Netlink API and driver facing API.
