power: supply: bq27xxx: synchronize work cancellation on suspend
The poll work requeues itself via mod_delayed_work() while the device
is not removed. cancel_delayed_work() does not wait for a callback
that is already running, so a poll racing with suspend can keep
issuing I2C transfers after suspend returns and requeue itself into
early resume.
Use cancel_delayed_work_sync() to quiesce polling before suspend
completes, as the teardown path already does.
Fixes: dfcb264a01a9 ("power: supply: bq27xxx: Stop and start delayed work in suspend and resume")
