usb: phy: twl6030-usb: fix possible use-after-free on remove
[ Upstream commit 5895d311d28f2605e2f71c1a3e043ed38f3ac9d2 ]
In remove(), use cancel_delayed_work_sync() to cancel the
delayed work. Otherwise there's a chance that this work
will continue to run until after the device has been removed.
This issue was detected with the help of Coccinelle.
