xenserver: Remove other_config option for setting controller.

Since XenServer 5.6, "vswitch_controller" has been a first-class key for
setting the Open vSwitch controller.  Prior to that, we stored it in
"other_config".  Since we no longer support such old versions, we can
remove references to the "other_config" option.
