[B.A.T.M.A.N.] [PATCH] batman-adv: return NULL instead of 0 in batadv_mcast_forw_ip_node_get()

batadv_mcast_forw_ip_node_get() returns a pointer, so returning NULL in error cases is always more appropriate than 0.

Introduced by: c8fedbea81eac41a4971bb43353fd52a903d7c4c ("batman-adv: Send multicast packets to nodes with a WANT_ALL flag")
