net/mlx5: Stop waiting for PCI if pci channel is offline

Browse source

[ Upstream commit 33afbfcc10 ]

In case pci channel becomes offline the driver should not wait for PCI
reads during health dump and recovery flow. The driver has timeout for
each of these loops trying to read PCI, so it would fail anyway.
However, in case of recovery waiting till timeout may cause the pci
error_detected() callback fail to meet pci_dpc_recovered() wait timeout.
