I will add devlink notifications for the counters, but what I meant here 
is to have counters data updated also on hosts that are having reset but 
didn't trigger the fw_activate action by themselves, so such host's 
devlink is not aware of it. I mean fw_activate action was triggered on 
another's host devlink sharing the same device/firmware.

Maybe I should have named this function 
devlink_reload_implicit_actions_performed().
