udp6: add missing rehash callback to udplite
After commit 23b0269e58ae ("net: udp6: prefer listeners bound to an
address"), UDP-Lite only works when specifying a local address for
the sockets.
This is related to the problem addressed in the commit 719f835853a9
("udp: add rehash on connect()"). Moreover, __udp6_lib_lookup() now
looks for a socket immediately in the secondary hash table.
And this issue was found with LTP/network tests as well.
Fixes: 23b0269e58ae ("net: udp6: prefer listeners bound to an address")
