batman-adv: don't pass a NULL hard_iface to batadv_hardif_put
In the case where hard_iface is NULL, the error path may pass a null
pointer to batadv_hardif_put causing a null pointer dereference error.
Avoid this by only calling the function if hard_iface not null.
Detected by CoverityScan, CID#1466456 ("Explicit null dereferenced")
Fixes: 53dd9a68ba68 ("batman-adv: add multicast flags netlink support")
