[PATCH] fbcon: Avoid corrupting active workqueue entries

We attempt to reschedule an active work which can itself corrupt the workqueue lists, and we may then free the work item whilst the task is still pending. Both of these may lead to a system deadlock and an unresponsive machine without any outputs for a panic to even be shown. [7.372961] WARNIN
