Subject: [PATCH net] devlink: Fix devlink_param_driverinit_value_set() stub return code

The stub function returned -EOPNOTSUPP while CONFIG_NET_DEVLINK is off.
It caused false warning during driver load. Driver needs to update
devlink on a parameter value if devlink module is there, if not it
doesn't need any error code.

Fixes: ec01aeb1803e ("devlink: Add support for get/set driverinit value")
