VM: [Kernel] Revert changes to the native ports that introduced peers.

The problem with these changes was that closed ports still continue to receive
messages and as a result we start using dead peer objects.

Fixing that would require more intrusive changes into message handler implementation - so instead we are reverting the changes and restoring manual PORT -> PEER mapping.
