power: supply: qti_battery_charger: Fix FCC configuration

With adding support to restricted charging through properties
restricted_chg and restricted_cur under /sys/class/qcom-battery,
configuring fast charging current (FCC) via "charge_control"
property in battery power supply is not working as expected.
Especially, when the restricted charging is disabled, FCC
configured (i.e. after setting it in ascending order first and
in descending order) is based on the previous request instead of
the current request. Fix it.
