batman-adv: fix multicast counter when purging originators
When purging an orig_node we should only decrease counter tracking the
number of nodes without multicast optimizations support if it was
increased through this orig_node before.
A not yet quite initialized orig_node (meaning it did not have its turn
in the mcast-tvlv handler so far) which gets purged would not adhere to
this and will lead to a counter imbalance.
Fixing this by adding a check whether the orig_node is mcast-initalized
before decreasing the counter in the mcast-orig_node-purging routine.

batman-adv: fix counter for multicast supporting nodes
A miscounting of nodes having multicast optimizations enabled can lead
to multicast packet loss in the following scenario:
If the first OGM a node receives from another one has no multicast
optimizations support (no multicast tvlv) then we are missing to
increase the counter. This potentially leads to the wrong assumption
that we could safely use multicast optimizations.
Fixings this by increasing the counter if the initial OGM has the
multicast TVLV unset, too.

batman-adv: fix lock class for decoding hash in network-coding.c
batadv_has_set_lock_class() is called with the wrong hash table as first
argument (probably due to a copy-paste error), which leads to false
positives when running with lockdep.
