Subject: [net-next 10/11] net/mlx5: E-Switch, Fix the warning on vport index out of range

From: Bodong Wang <bodong@...lanox.com>

When eswitch gets vport data structure, the index should not be out
of the range of the vport array. Driver mistakenly used vport number
to check the range.

Fixes: 22b8ddc86bf4 ("net/mlx5: E-Switch, Assign a different position for uplink rep and vport")
