generate key ext: skip driver invocation with non-default method

In the driver wrapper for psa_generate_key() and psa_generate_key_ext():

* Invoke the built-in code if using a non-default method, even if there
  might be an accelerator. This is ok because we only support non-default
  methods for RSA and we don't support driver-only RSA, therefore a
  non-default method will always have built-in code behind it.
* Return NOT_SUPPORTED if trying to use a non-default method with an opaque
  driver.
