Revert "Integrate replica in the qemu migration."

Browse Source 
This reverts commit 63d02c7074.

The commit changes the configuration before the VM is actually
migrated, so it is possible to have a wrong configuration when
migration fails for some reason. Also, I am quite unsure if
this automatic target change is really wanted. The patch also
contains wrong refereces to $self->{opts}->{node}.
