Subject: RDMA/netlink: Rename and remove redundant parameter from
 ibnl_multicast
Patch-mainline: v4.14-rc1
Git-commit: 4d7f693af0c9d0d6940ff36f5adca1adfa0e7e6e
References: bsc#1046306 FATE#322942

The pointer to netlink header was not used in the ibnl_multicast
function, so let's remove it and simplify the function
signature.
