[RFC net-next 09/15] devlink: health: combine loops in dump

[Jakub Kicinski <kuba@kernel.org>]

Walk devlink instances only once. Dump the instance reporters
and port reporters before moving to the next instance.
User space should not depend on ordering of messages.

This will make improving stability of the walk easier.
