batman-adv: only modify hna-table on active module
If we haven't set the module to MODULE_ACTIVE state before (in general,
no interface has yet been added to batman-adv) then the hna table is not
initialised yet. If the kernel changes the mac address of the bat0
interface at this moment then an hna_local_add() called by interface_set_mac_addr()
then resulted in a null pointer derefernce. With this patch we are now
explicitly checking before if the state is MODULE_ACTIVE right now so
that we can assume having an initialised hna table.

commit 2f51b1c529d9f3d5654e41e6e08b8ba769e786f7

Staging: batman-adv: fix unlock, make code sparse clean
If the skb failed to copy in the (batman) icmp receive handlers, the function
returned without unlocking the orig_hash_lock first. To prevent this,
the fields needed from the orig_node are now copied, and the copies are
used for sending (just like in other handlers).
Furthermore, find_batman_if() was declared static. The code now appears
to be clean in 'sparse' [1].
Thanks to Andrew Lunn for pointing that out.

batctl is extended to recognize the -R option for the ping subcommand.
The output should be the same as for the standard iputils ping program.
For this, the destination host is printed twice.

batman-adv: record route for ICMP messages
The standard layer 3 ping utility can use the record route (RR) option
of IP to collect route data for sent ping messages (ping -R). This
patch introduces comparable functionality for batman-adv ICMP messages.
The patch adds a second batman ICMP packet format (icmp_packet_rr) such
that up to 17 MAC addresses can be recorded (sufficient for up to 8
hops per direction). When no RR is wanted, the old icmp_packet without
the RR overhead can be sent.

it before searching with hash_find().
