power: qpnp-smbcharger-mmi: Fix Full Condition

Browse source 
Make sure to charge back if battery drops to 99%.
This was found beucase after charge FULL the Flip battery
still needed charge to balance voltage.  The Main battery
charged the Flip battery.  Then Main battery hits 99% but
because Flip was FULL it was blocked from restarting the
Charge controller.
