net/mlx5e: Fix crash in recovery flow without devlink reporter

Browse source

commit 1ad6c43c6a 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.

Internal error: Oops: 96000007 [#1] PREEMPT SMP
