Staging: batman-adv: don't have interrupts disabled while sending.
send_vis_packets() would disable interrupts before calling
dev_queue_xmit() which resulting in a backtrace in local_bh_enable().
Fix this by using kref on the vis_info object so that we can call
send_vis_packets() without holding vis_hash_lock. vis_hash_lock also
used to protect recv_list, so we now need a new lock to protect that
instead of vis_hash_lock.
Also a few checkpatch cleanups.
