[PATCH] [v2] power: supply: bq24190_charger: Fix runtime PM imbalance on error

[Dinghao Liu]

pm_runtime_get_sync() increments the runtime PM usage counter even
it returns an error code. Thus a pairing decrement is needed on
the error handling path to keep the counter balanced.

Changelog:

v2: - Use pm_runtime_put_noidle() rather than
      pm_runtime_put_autosuspend().
