power: qpnp-fg-gen3: Adjust recharge SOC after early termination

Currently, recharge SOC is adjusted based on the SOC at which
charge termination occurs. However, it gets reset back to the
original threshold only if input is removed. This does not work
well if charging resumes again once the battery is out of JEITA
as the recharge SOC threshold stays configured at a lower value.
Fix it by adjusting recharge SOC to the original threshold once
charging begins.
