[PATCH 2/4] batman-adv: Remove redundant 'flush_workqueue()' calls

[Simon Wunderlich]

From: Christophe JAILLET <christophe.jail...@wanadoo.fr>

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

Remove the redundant 'flush_workqueue()' calls.

This was generated with coccinelle:

-       flush_workqueue(E);
        destroy_workqueue(E);
