power: qpnp-fg-gen3: Restore recharge SOC only when not in JEITA 



Currently, recharge SOC is adjusted (lowered) based on the SOC
where charging terminates. It is restored back to the original
threshold when the charge termination condition goes away. This
works fine in most cases. However there are certain conditions
where the charger fluctuates between fast and taper regions along
with the charge termination status.

Handle this by checking if battery is out of JEITA as well before
restoring back the original recharge SOC threshold.
