Subject: devlink: add support for reporter recovery completion
Patch-mainline: v5.6-rc1
Git-commit: 6181e5cb752e5de9f56fbcee3f0206a2c51f1478
References: bsc#1154353

It is possible that a reporter recovery completion do not finish
successfully when recovery is triggered via
devlink_health_reporter_recover as recovery could be processed in
different context. In such scenario an error is returned by driver when
recover hook is invoked and successful recovery completion is
intimated later.
Expose devlink recover done API to update recovery stats.
