Make the code using filter function a bit nicer by consolidating the
filter function arguments using typedef.

Suggested-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com>
Signed-off-by: Jiri Pirko <jiri@nvidia.com>
---
v2->v3:
- left the original .c and .h arg names and types
  inconsistencies for cn_netlink_send_mult() and
  netlink_broadcast_filtered()
v1->v2:
- new patch
