Ihar Hrachyshka c3b9c44f36 Flip ovn_emit_need_to_frag to True by default
Setting it to False is relevant only for older kernels.

Major distros ship the necessary kernel for a while, e.g. Ubuntu LTS has
5.2 since 20.04.0. RHEL ships 5.14.0 (+backports) since 9.0.

The ``ovn_emit_need_to_frag`` option for OVN is now enabled by default.
This may result in performance issues on older kernels (older than 5.2). If
you are still using an old kernel, you may consider setting it to
``False``.
