Subject: [PATCH net-next] devlink: Add health recover notifications on devlink flows

Devlink health recover notifications were added only on driver direct
updates of health_state through devlink_health_reporter_state_update().
Add notifications on updates of health_state by devlink flows of report
and recover.

Fixes: 97ff3bd37fac ("devlink: add devink notification when reporter update health state")
