cxgb4 Ethernet driver now queries PCIe configuration space to determine
if it can send TLPs to it with the Relaxed Ordering Attribute set.

Remove the enable_pcie_relaxed_ordering() to avoid enable PCIe Capability
Device Control[Relaxed Ordering Enable] at probe routine, to make sure
the driver will not send the Relaxed Ordering TLPs to the Root Complex which
could not deal the Relaxed Ordering TLPs.

Ding,

You can probably just drop this patch. If I am understanding Casey
correctly just the fact that the relaxed ordering enable bit is
cleared in the configuration should be enough to do this for the
device automatically.

Actually I take that back. I hadn't caught the most recent parts of
the thread. If this is good for Casey then this works for me.
