rgmanager: Fix relocation & migration errors
rgmanager: Fix relocation & migration errors

If you relocate a service but in the end, it ends
up on the same node, the error message was "Failure".

While technically correct because the relocation
failed, there really is no reason to not have an
error to indicate the condition that the service
is still running.

Furthermore, during migration, if a migration had
a non-critical failure causing the migration to
fail but leaving a virtual machine running on the
original owner, there was no method to detect this
particular condition.
