Removing start_ovn_services call

The function _start_ovn is responsible for starting the
OVS/OVN services. However, its final action is a call
to _start_ovn_services, which restarts all OVS/OVN services
without any justified reason.

This patch removes that call to avoid unnecessarily
restarting all OVS/OVN services immediately after they
have been started.
