Subject: [PATCH] power: supply: axp288_charger: Do not cancel work before
 initializing it

Driver registered devm handler to cancel_work_sync() before even the
work was initialized, thus leading to possible warning from
kernel/workqueue.c on (!work->func) check, if the error path was hit
before the initialization happened.

Use devm_work_autocancel() on each work item independently, which
handles the initialization and handler to cancel work.
