Ido Schimmel 9b3bc7db75 mlxsw: core: Fix use-after-free when flashing firmware during init ... When the switch driver (e.g., mlxsw_spectrum) determines it needs to flash a new firmware version it resets the ASIC after the flashing process. The bus driver (e.g., mlxsw_pci) then registers itself again with mlxsw_core which means (among other things) that the device registers itself again with the hwmon subsystem again. Since the device was registered with the hwmon subsystem using devm_hwmon_device_register_with_groups(), then the old hwmon device (registered before the flashing) was never unregistered and was referencing stale data, resulting in a use-after free. Fix by removing reliance on device managed APIs in mlxsw_hwmon_init().
