soc: qcom: Reset watchdog before setting bite time

Browse source 
Reset watchdog before setting bite time in watchdog panic
handler. If the watchdog’s bite time is reduced below its
current count, there is a possibility that it will bite as
the virtual watchdog sets times relative to the last pet.
