power: supply: charger-manager: Switch to alarm_start_timer()

Browse Source 
The existing alarm_start() interface is replaced with the new
alarm_start_timer() mechanism, which does not longer queue an already
expired timer and returns the state. Adjust the code to utilize this.

No functional change intended.
