[ovs] Reload ovs kernel module always

Irrespective of build_modules is True
or False reload ovs modules always.

If ovs is installed from package before(like
with multi-node-bridge role), then installing
ovs from source requires openvswitch kernel
module to be reloaded.

The issue was not seen before jammy as there
module was reloaded when build_modules was set
to True.
