power: supply: max14656: fix potential use-after-free
[ Upstream commit 252fbeb86ceffa549af9842cefca2412d53a7653 ]
Explicitly cancel/sync the irq_work delayed work, otherwise
there's a chance that it will run after the device is removed,
which would result in a use-after-free.
Note that cancel/sync should happen:
- after irq's have been disabled, as the isr re-schedules the work
- before the power supply is unregistered, because the work func
uses the power supply handle.
