[PATCH 6.1.y] Revert "usb: phy: fsl-usb: Fix use-after-free in delayed work during device removal"

This reverts commit 4476c73bbbb09b13a962176fca934b32d3954a2e.

The reverted commit uses disable_delayed_work_sync, which was introduced
by commit 86898fa6b8cd ("workqueue: Implement disable/enable for
(delayed) work items") in v6.10. The function is therefore unavailable
in 6.1.y, causing configurations that enable CONFIG_FSL_USB2_OTG to fail
to build.

The upstream commit is unaffected; only its incompatible stable backport
is being reverted.
