[NET]: Make netlink processing routines semi-synchronious (inspired by rtnl) v2
The code in netfilter/nfnetlink.c and in ./net/netlink/genetlink.c looks
like outdated copy/paste from rtnetlink.c. Push them into sync with the
original.
Changes from v1:
- deleted comment in nfnetlink_rcv_msg by request of Patrick McHardy
