[B.A.T.M.A.N.] [PATCH 1/2] batman-adv: Fix broadcast queue limit on a removed interface

["Linus Lüssing" <linus.luessing@web.de>]

When removing a single interface while a broadcast or ogm packet is
still pending then we will free the forward packet without releasing the
queue slots again.

This patch is supposed to fix this issue.
