commit 1ad6c43c6a7b8627240c6cc19c69e31fedc596a7 upstream.
When health reporters are not supported, recovery function is invoked
directly, not via devlink health reporters.
In this direct flow, the recover function input parameter was passed
incorrectly and is causing a kernel oops. This patch is fixing the input
parameter.
Following call trace is observed on rx error health reporting.
