net/mlx5: fix LAG representor probing on PF1 PCI

Browse Source 
In case of bonding, orchestrator wants to use same devargs for LAG and
non-LAG scenario to probe representor on PF1 using PF1 PCI address
like "<DBDF_PF1>,representor=pf1vf[0-3]".

This patch changes PCI address check policy to allow PF1 PCI address for
representors on PF1.

Note: detaching PF0 device can't remove representors on PF1. It's
recommended to use primary(PF0) PCI address to probe representors on
both PFs.

Fixes: f926cce3fa94 ("net/mlx5: refactor bonding representor probing")
