From: Linus Lüssing <[email protected]>
commit c4fdb6cff2aa0ae740c5f19b6f745cbbe786d42f upstream.
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.

forw_packet_free")
