David S. Miller 3e8c806a08 Revert "tcp: disallow bind() to reuse addr/port" ...

This reverts commit c191a836a9.

It causes known regressions for programs that expect to be able to use
SO_REUSEADDR to shutdown a socket, then successfully rebind another
socket to the same ID.

Programs such as haproxy and amavisd expect this to work.

This should fix kernel bugzilla 32832.
