Subject: [PATCH 23/25] video/exynos: don't use [delayed_]work_pending()

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 exynos_dp_core.  Only compile
tested.

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

Thanks.
