ASoC: wsa881x: Avoid removing of already deleted timer object

Browse source 
Cancel_delayed_work_sync in wsa881x_swr_down function is trying to
remove the timer object which is already deleted. Check for
pending work before calling cancel_delayed_work_sync to avoid
unnecessary removal of timer object which is already deleted.
