netlink: Queue the kernel socket after setting the flag. 

Queueing the socket after setting the NETLINK_KERNEL_SOCKET on the
kernel socket.

This change is required in-order to avoid the BUG check which is
caused due to race condition between setting this flag and a
message from the app space for this kernel netlink sock.
