Getting timeout message from BMC when trying to read from a non-existent
FRU. This is expected but warning is not.

Let's reduce the warning to debug.

Why would a timeout for a message be expected?  The BMC should
at least respond with an error for an incorrect message.

Let me add some more context...

In this particular case, the FRU ID that I was trying to access was
correct. 

Platform supports PCIe hotplug. The FRU is embedded into the HW that
is being removed. That's what I mean by non-existent.

When the device is ejected and a FRU command is executed, BMC times out
reaching to the FRU on the device. 

When the device is inserted, everything works as expected.

I haven't added this yet.  Someone who knows more about the ACPI side of 
IPMI
should probably comment.  So I've added Lv Zheng.

This is ok with me, though.  If you remove a management controller, a 
timeout is
expected.  However, if the management controller is still present, a 
timeout is
probably not the best error code, "destination unavailable" is probably 
a better
choice.
