3.16.36-rc1 review patch. If anyone has any objections, please let me know.
------------------
From: Linus Lüssing <linus.luessing@xxxxxxxxx>
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.
Fixes: 6d5808d4ae1b ("batman-adv: Add missing hardif_free_ref in forw_packet_free")
