X-Git-Tag: firefly_0821_release~3680^2~1480^2~48^2~6

tipc: change sk_receive_queue upper limit

The sk_recv_queue upper limit for connectionless sockets has empirically
turned out to be too low. When we double the current limit we get much
fewer rejected messages and no noticable negative side-effects.
