mb/google/nissa: Fix potential null pointer dereference
* Introduce a null check before calling `gpio_padbased_override`
in `variant_configure_pads`.
* This prevents potential errors in cases where the
`variant_gpio_override_table` function returns a null pointer,
indicating that there are no override pads to configure.
BUG=b:334826281
TEST=Able to avoid hang incase there is no GPIO override.
