ASoC: wcd934x-dsp-cntl: notify online event after clocks are disabled

The moment the online event is notified to userspace, it may happen that
the userspace might enable the WDSP. This causes race between the
enabling of WDSP and SSR handling of WDSP. Change the sequence to notify
online event after all SSR handling is completed.
