power: supply: bq24190_charger: Fix runtime PM imbalance on error

Browse source 
[ Upstream commit 1a37a039711610dd53ec03d8cab9e81875338225 ]

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.
