power: supply: bq25890: Ensure pump_express_work is cancelled on remove
[ Upstream commit a7aaa80098d5b7608b2dc1e883e3c3f929415243 ]
The pump_express_work which gets queued from an external_power_changed
callback might be pending / running on remove() (or on probe failure).
Add a devm action cancelling the work, to ensure that it is cancelled.
Note the devm action is added before devm_power_supply_register(), making
it run after devm unregisters the power_supply, so that the work cannot
be queued anymore (this is also why a devm action is used for this).
Fixes: 48f45b094dbb ("power: supply: bq25890: Support higher charging voltages through Pump Express+ protocol")
