net/mlx5: Do not query pci info while pci disabled

[ Upstream commit 394164f9d5a3020a7fd719d228386d48d544ec67 ]

The driver should not interact with PCI while PCI is disabled. Trying to
do so may result in being unable to get vital signs during PCI reset,
driver gets timed out and fails to recover.
