power_supply: Don't use flush_scheduled_work()

Browse source 
flush_scheduled_work() is deprecated and scheduled to be removed.

In battery drivers, the work can be canceled on probe failure and
removal and should be flushed on suspend.  Replace
flush_scheduled_work() usages with direct cancels and flushes.
