ASoC: SOF: control: skip rpm calls in ext_volatile_get if not implemented
Test earlier for the existence of ext_volatile_get callback and if it is
missing, skip the rpm calls to avoid needles DSP power on.
No change in functionality, we just skip the DSP power on in the unlikely
case when the ext_volatile _get is not supported and yet the topology adds
such control.
