VMCI: Fix process-to-process DRGAMs.

Browse source 
When sending between processes, we always schedule a work item.  Our work info
struct has the message embedded in the middle, which means that we end up
overwriting subsequent fields when we copy the (variable-length) message into
it.  Move it to the end of the struct.
