Subject: [PATCH net-next 06/10] mlxsw: core_thermal: Make mlxsw_thermal_module_{init, fini} symmetric

From: Ido Schimmel <idosch@...dia.com>

mlxsw_thermal_module_fini() de-initializes the module's thermal zone,
but mlxsw_thermal_module_init() does not initialize it. Make both
functions symmetric by moving the initialization of the module's thermal
zone to mlxsw_thermal_module_init().
