Subject: [net-next V2 12/13] net/mlx5: Fix query_nic_sys_image_guid() error during init

From: Aviv Heller <avivh@...lanox.com>

vport system image guid should be queried using vport nic API for
Ethernet ports, and vport hca API for Infiniband ports.

Fixes: fadd59fc50d0 ("net/mlx5: Introduce inter-device communication mechanism")
