Bug #13343
some mlxcx devices don't support temperature sensors
100%
Description
The Mellanox ConnectX-4 lx (15b3,1015), unlike other parts, appears not to have a built-in temperature sensor. Unfortunately, there's no actual way for us to tell this in the hardware through what documentation we have (what does exist like the warning event is supported by folks who have the device). Because of the way the driver is structured, this causes attach to fail. Instead, we should just not create the temperature nodes and drive on when we hit this case.
This was tested by folks at RackTop who had the ConnectX-4 Lx and hit this.

This was tested in two ways. Paul at Racktop verified that this caused us to correctly attach regardless of presence. Alex verified that the temperature sensors still work.
