drivers/net: don't use flush_scheduled_work()
flush_scheduled_work() is on its way out. This patch contains simple
conversions to replace flush_scheduled_work() usage with direct
cancels and flushes.
Directly cancel the used works on driver detach and flush them in
other cases.
The conversions are mostly straight forward and the only dangers are,
* Forgetting to cancel/flush one or more used works.
* Cancelling when a work should be flushed (ie. the work must be
executed once scheduled whether the driver is detaching or not).
I've gone over the changes multiple times but it would be much
appreciated if you can review with the above points in mind.
