[PATCH net-next 6/7] tools: ynl: cli: extract the event/notify handling in --list-attrs

[Jakub Kicinski <kuba@kernel.org>]

Event and notify handling is quite different from do / dump
handling. Forcing it into print_mode_attrs() doesn't really
buy us anything as events and notifications do not have requests.
Call print_attr_list() directly. Apart form subjective code
clarity this also removes the word "reply" from the output:

Before:

  Event reply attributes:

Now:

  Event attributes:
