Revert "tcp: disallow bind() to reuse addr/port"
This reverts commit c191a836a908d1dd6b40c503741f91b914de3348.
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.
