charger-manager: Fix bug when check dropped voltage after fullbatt event
This patch check difference value between current voltage of battery and
desc->fullbatt_uV whether positve or negative number. If difference value
is negative number when current voltage of battery is larger than
desc->fullbatt_uV, charger-manager return immediately because battery is
fully charged.
