xenserver: Update Open vSwitch post upgrade instructions.

Currently, when we upgrade the userspace rpm for XenServer,
we print a message asking users to reboot the hypervisor.
This is not needed. The reboot of hypervisor is needed when
we upgrade the rpm containing the kernel module.  This
reboot can sometimes be avoided by running a
"service openvswitch force-reload-kmod".
