We currently have a bug in the PRD code, where the contents of an
incoming message (beyond the header) will be overwritten by the list
item manipulations when adding to to the prd_msg_queue.
This change reorders struct opal_prd_msg_queue_item, so that the
message body doesn't overlap the list_head.
We also clarify the memcpy of the message, as we're copying unnecessary
bytes at the end of the message data.
