udp: fix for unicast RX path optimization
Commits 5051ebd275de672b807c28d93002c2fb0514a3c9 and 5051ebd275de672b807c28d93002c2fb0514a3c9 ("ipv[46]: udp: optimize unicast RX path") broke some programs. After upgrading a L2TP server to 2.6.33 it started to fail, tunnels going up an down, after the 10th tunnel came up. My modified rp-l2tp uses a global unconnected socket bound to (INADDR_ANY, 1701) and one connected socket per tunnel after parameter negotiation. After ten sockets were open and due to mixed parameters to udp[46]_lib_lookup2() kernel started to drop packets.
