[Skiboot] [PATCH v3 2/3] core/ipmi: Add ipmi sync messages to top of the list

[Vasant Hegde]

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.
