netlink: add netlink_dump_control structure for netlink_dump_start()
Davem considers that the argument list of this interface is getting out of control. This patch tries to address this issue following his proposal: struct netlink_dump_control c = { .dump = dump, .done = done, ... }; netlink_dump_start(..., &c); Suggested by David S. Miller.
