The comment about providing a proper message seems similar to
the comment in the kernel which says:
/* hack -- fix at some point with proper message
This is how we indicate to tc that there is no VQ
at this DP */
it's unclear what that message would be, and whether it's needed.
Remove the confusing comment.

Do you really need this? it turns out that because of C type conversions print_uint should just
work?

I wondered about that for a second, but I took the existence of
jsonw_hu_field() etc. as a proof that explicit typing is preferred.

Number of qdiscs use the same set of flags to control shared RED
implementation. Add a helper for printing those flags.
