power: supply: bq25890: Fix power_supply reference leak
bq25890_fw_probe() acquires a reference to a secondary charger using
power_supply_get_by_name(), but the reference is not released on later
probe failures or on driver detach.
In particular, failures after bq25890_fw_probe() returns successfully,
such as a failure in bq25890_hw_init(), also leak the reference.
Register a device-managed cleanup action immediately after acquiring
the secondary charger. This releases the reference on all subsequent
probe failures and on driver detach.
Found by code review.
