core/ipmi: Add ipmi sync messages to top of the list
[ Upstream commit 968c30905d7a61d777606a5f5c7949027564efd8 ]
In ipmi_queue_msg_sync() path OPAL will wait until it gets response from
BMC. If we do not get response ontime we may endup in kernel hardlockups.
Hence lets add sync messages to top of the queue. This will reduces the
chance of hardlockups.
