power: supply: sbs-charger: Don't cancel work that is not initialized
This driver can use an interrupt or polling in order get the charger's
status.
When using polling, a delayed work is used.
However, the remove() function unconditionally call
cancel_delayed_work_sync(), even if the delayed work is not used and is not
initialized.
In order to fix it, use devm_delayed_work_autocancel() and remove the now
useless remove() function.
