ASoC: dapm: Fix race condition for widgets power list creation
Multiple calls to dapm_power_widgets() can create a race condition
causing widget power list to be corrupted. Those scenarios can
occur in multistream usecases, stream start/stop along with update
power calls (mixer, mux, dapm_sync, stream_event) simultaneously.
