[B.A.T.M.A.N.] [PATCHv3 next 03/11] batman-adv: fix multicast kerneldoc

[Antonio Quartulli <antonio@meshcoding.com>]

The kerneldoc should always use the third person singular in
the long function description.
Moreover it should always try use up to 80 chars per line.

Introduced by 86cb16e5ec1e2d75821006e8f4abbec66fb741ac
("batman-adv: Add IPv4 link-local/IPv6-ll-all-nodes multicast support")
