Eric DumazetandGreg Kroah-Hartman 18897db751 tcp: fix __tcp_close() to only send RST when required ...

[ Upstream commit 5f92385309 ]

If the receive queue contains payload that was already
received, __tcp_close() can send an unexpected RST.

Refine the code to take tp->copied_seq into account,
as we already do in tcp recvmsg().
