net: sparx5: Fix initialization of variables on stack

The variables 'res' inside the functions sparx5_ptp_get_1ppm and
sparx5_ptp_get_nominal_value was not initialized. So in case of the default
case of the switch after, it would return an uninitialized variable.
This makes also the clang builds to failed.
