Armin Wolf 066b90bca7 ACPI: EC: Fix oops when removing custom query handlers ...

[ Upstream commit e5b492c6bb900fcf9722e05f4a10924410e170c1 ]

When removing custom query handlers, the handler might still
be used inside the EC query workqueue, causing a kernel oops
if the module holding the callback function was already unloaded.

Fix this by flushing the EC query workqueue when removing
custom query handlers.

Tested on a Acer Travelmate 4002WLMi
