backport: Add genl_callback_extack() function
The struct netlink_callback got a new extack attribute in commit
4a19edb60d02 ("netlink: Pass extack to dump handlers") in kernel 4.20.
Use a function instead of directly accessing it to return NULL on older
kernel versions, the code should handle NULL.
