[PATCH] ieee802154: Remove redundant 'flush_workqueue()' calls

'destroy_workqueue()' already drains the queue before destroying it, so
there is no need to flush it explicitly.

Remove the redundant 'flush_workqueue()' calls.

Hello Dave, Jakub.

I have nothing else in my ieee802154 tree for net right now so it would 
be great if you could take it directly. If that poses a problem, let me 
know and I will get it in through my tree.

Do you mean net or net-next? This looks like net-next material.

Just to be sure, applying directly is not a problem.

Yes, net-next, please.
