vmm: streamline migration related API error variants

Browse Source 
Receiving a migration happens inside the VMM thread, which blocks the
API until a migration was received. On the other hand, sending a
migration is actually just a dispatch operation. We adjust the wording
to improve clarity of the error messages.
