Revert "tcp: bind() fix when many ports are bound"

Browse source 
This reverts two commits:

fda48a0d7a
tcp: bind() fix when many ports are bound

and a follow-on fix for it:

6443bb1fc2
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.
