xenserver: Remove now-unsupported commands from /etc/init.d/vswitch.

The "unload" and "update-modules" commands for /etc/init.d/vswitch were
based on the files in /etc/sysconfig/network-scripts.  The current
implementation of interface-reconfigure no longer updates those files, so
these commands would no longer work reliably.  Worse, they would work
*sometimes* but not other times, so it's better not to offer them at all.

It might make sense to reimplement these, if they are useful enough.
