Ben Hutchings 5c97f6d487 Revert "sfc: Use write-combining to reduce TX latency" and follow-ups ...

[ Upstream commit 86c432ca5d6da90a26ac8d3e680f2268b502d9c5 ]

This reverts commits 65f0b417de,
d88d6b05fe,
fcfa060468,
747df2258b and
867955f568.

Depending on the processor model, write-combining may result in
reordering that the NIC will not tolerate.  This typically results
in a DMA error event and reset by the driver, logged as:

sfc 0000:0e:00.0: eth2: TX DMA Q reports TX_EV_PKT_ERR.
sfc 0000:0e:00.0: eth2: resetting (ALL)
