net: phy: tja11xx: remove call to devm_hwmon_sanitize_name

Since c909e68f8127 ("hwmon: (core) Use device name as a fallback in
devm_hwmon_device_register_with_info") we can simply provide NULL
as name argument.

Note that neither priv->hwmon_name nor priv->hwmon_dev are used
outside tja11xx_hwmon_register.
