Subject: [net-next V4 08/15] net/mlx5: remove fw reporter dump option for non PF

From: Moshe Shemesh <moshe@...dia.com>

In case function is not a Physical Function it is not allowed to get FW
core dump, so if tried it will fail the fw health reporter dump option.
Instead of failing, remove the option of fw_fatal health reporter dump
for such function.
