Revert "tcp: bind() fix when many ports are bound"
This reverts two commits:
fda48a0d7a8412cedacda46a9c0bf8ef9cd13559
tcp: bind() fix when many ports are bound
and a follow-on fix for it:
6443bb1fc2050ca2b6585a3fa77f7833b55329ed
ipv6: Fix inet6_csk_bind_conflict()
It causes problems with binding listening sockets when time-wait
sockets from a previous instance still are alive.
It's too late to keep fiddling with this so late in the -rc
series, and we'll deal with it in net-next-2.6 instead.
