VMCI: Fix process-to-process DRGAMs.
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.
