HA: fix race when moving VIP during minor update

During a minor update of a controller node, we list the
VIP hosted on the node and we force them to move away
with a pcs command.

The way we call the pcs command is racy, so change the
action to make sure the VIP move is performed only if
the VIP is still hosted on the node when we run the action.
