wifi: iwlwifi: honor the enable_ini value

In case the user sets the enable_ini to some preset, we want to honor
the value.

Remove the ops to set the value of the module parameter is runtime, we
don't want to allow to modify the value in runtime since we configure
the firmware once at the beginning on its life.
