There's no need to test whether a (delayed) work item in pending
before queueing, flushing or cancelling it. Most uses are unnecessary
and quite a few of them are buggy.
Remove unnecessary pending tests from thinkpad_acpi. Only compile
tested.

Please let me know how this patch should be routed. I can take it
through the workqueue tree if necessary.
Thanks.
