Subject: [net-next V4 07/15] net/mlx5: remove fw_fatal 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 collect
crdump, so if tried it will fail the fw_fatal health reporter dump
option. Instead of failing on permission, remove the option of fw_fatal
health reporter dump for such function.
