qcom: smblib: report discharging in case of input OV 



The register BATTERY_CHARGER_STATUS continues to show charging state
(like FULLON or TAPER mode) in cases where charging was paused due
to input OV. Look at BATTERY_CHARGER_STATUS_7_REG to determine if
charging was paused.

This fix modifies previous similar change for JEITA hard condition but
continue to cover the case.
