power: supply: bq24190_charger: fix reference leak 

[ Upstream commit b2f6cb78ea ]

pm_runtime_get_sync will increment pm usage counter even it
failed. Forgetting to call pm_runtime_put_noidle will result
in reference leak in callers(bq24190_sysfs_show,
bq24190_charger_get_property, bq24190_charger_set_property,
bq24190_battery_get_property, bq24190_battery_set_property),
so we should fix it.
