devlink: Implicitly set auto recover flag when registering health reporter

Browse Source 
When health reporter is registered to devlink, devlink will implicitly set
auto recover if and only if the reporter has a recover method. No reason
to explicitly get the auto recover flag from the driver.

Remove this flag from all drivers that called
devlink_health_reporter_create.

All existing health reporters set auto recovery to true if they have a
recover method.

Yet, administrator can unset auto recover via netlink command as prior to
this patch.
