Native async TLS connections log "returning true from eof_received() has no effect when using ssl

Native async TLS connections log a warning : returning true from eof_received() has no effect when using ssl whenever the server closes the connection. No functional impact: the connection closes correctly either way. it's only misleading log noise.

Cause: the in-band TLS upgrade uses loop.start_tls(), which doesn't re-run connection_made, so StreamReaderProtocol._over_ssl stays False; eof_received() then returns True (requesting a half-open connection), which asyncio ignores over SSL and warns about.
