workqueue: implement mod_delayed_work[_on]()
Workqueue was lacking a mechanism to modify the timeout of an already pending delayed_work. delayed_work users have been working around this using several methods - using an explicit timer + work item, messing directly with delayed_work->timer, and canceling before re-queueing, all of which are error-prone and/or ugly. This patch implements mod_delayed_work[_on]() which behaves similarly to mod_timer() - if the delayed_work is idle, it's queued with the given delay; otherwise, its timeout is modified to the new value. Zero @delay guarantees immediate execution. v2: Updated to reflect try_to_grab_pending() changes. Now safe to be called from bh context.
