Well, the crash6 looks strange in following way:
1) tcp_usr_listen seems to be called on a same inp twice
2) an "accepted" tcp socket is duplicated onto the wildcardhash and it
seems to be linked into connhash too.  The socket is in FIN_WAIT_1

crash6 is caused by 2), though 1) was problematic too

I will add some assertion, so the panic could happen earlier
