Subject: [PATCH 24/40] abx500-chargalg: Prevent the watchdog from being kicked twice

Charging watchdog kicker work-thread gets started twice causing
'failed to kick watchdog' message after removing charger and
when re-inserting charger. This patch removes the superfluous
start of watchdog kicker-thread.
