[Bridge] [RFC PATCH net-next 02/13] bridge: mcast: Remove pointless sequence generation counter assignment

[Ido Schimmel <idosch@nvidia.com>]

The purpose of the sequence generation counter in the netlink callback
is to identify if a multipart dump is consistent or not by calling
nl_dump_check_consistent() whenever a message is generated.

The function is not invoked by the MDB code, rendering the sequence
generation counter assignment pointless. Remove it.

Note that even the function was invoked, we still could not accurately
determine if the dump is consistent or not, as there is no sequence
generation counter for MDB entries, unlike nexthop objects, for example.
