[PATCH v2 2/6] ASoC: SDCA: drop pm_runtime reference on probe failure path

[Srinivas Kandagatla]

sdca_class_probe() takes an extra usage count with
pm_runtime_get_noresume() to keep the device powered on until the
deferred boot work has run. If devm_pm_runtime_enable() then fails,
that reference is never dropped.

Drop it on the error path.
