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.
Moved functions devlink_nl_health_reporter_fill() and
devlink_recover_notify() to avoid forward declaration.
Fixes: 97ff3bd37f ("devlink: add devink notification when reporter update health state")
